I have an emulator in eclipse.
Did i need another things?
Excel stores time internally the same way as date - i.e. 1 equals one full day, namely January 1st, 1900. Thus, one hour is 1/24. Assuming that only the time was entered into the cell (and not a full date with a time), you could therefore use this formula:
=IF(U7>16/24+50/(24*60),U7-(16/24+50/(24*60)),0)
Alternatively, you could use Excel's TIME function, which converts hours, minutes and seconds into an Excel time:
=IF(U7>TIME(16,50,0),U7-TIME(16,50,0),0)
In case your input cell is a full date with a time, you need to either get rid of the date in the input value - or add the date to the comparison - though I'd recommend the former:
=IF(TIME(HOUR(U7),MINUTE(U7),SECOND(U7))>TIME(16,50,0),U7-TIME(16,50,0),0)
Go through the following article, I hope this will help you.
compare time in excel
You should compare time in following way -
U7>TIME(16,50,0) inside the IF condition.
Please make sure that the column U7 which you use as time input, should be in proper Time format.
Thanks.

I have a gate keeping report with a number of entry/exit times for an employee over a 24hr period.
I need another formula to go into I40 which is the difference between the first entry time - last entry time for each employee eg. I40 = F50 - D40.
Dont worry about the formula regarding the subtraction of dates as I have this. I really just need the formula that will allow me to get the Last Exit time cell and the First Entry time cell for each employee.
The best way is to always store datetime values (ie, 2018-05-24 13:454) instead of just the times. You could still display it as a time by changing the cell's formatting to a time format.
Shortcut to Number Formatting options: Ctrl+1
There are many advantages, including that "regular math" will still work even if a shift starts in a different day than it ends.
If you must stick with only times, you can still calculate it correctly (up to a 23.9-hour shift) with an IF statement to add a day if the returned value is negative.
For example, if your existing formula works for same-day shift, and is:
=F50-D40
...then you could change it to:
=IF(F50-D40<0,F50+1-D40,F50-D40)

EDIT:
Looking at your question again, perhaps I misunderstood what you were trying to ndo. It's a little unclear, but you mention the fist and last times.
If you mean the "earliest and latest", you can get those using MIN and MAX. If the crossing-midnight is an issue here too, you'll need to see my first suggestion above, or else add a "helper column" to determine which times are before which.
Storing datetime is still best and this all would have been avoided.
try the below to get the difference in hours.
=(E50+F50)-(C40+D40)
I'm working on an excel 2010 sheet where I mark down the date and time an event happens. The date is in one column, and auto formats to 17-Nov when I would type in 11-17 (I was fine with this). The time is in a separate column.
I am trying to find the average time an event occurred, without regard to the date, so I would use =AVERAGE(C1:C10). However, I only receive a date back (like 17-APR).
I did not format the cells before I began to enter in data, and I would simply type in a 3:27pm event as 1527, and no reformatting would happen.
Now, when I attempt to reformat the column to hhmm, all the numbers entered so far turn to 0000. When I try to edit the 0000, it is formatted as 6/13/1906 12:00:00 AM.
What I want to do is have the time formatted as hhmm and not include a date in the cell, and be able to run formulas on it, such as the average time an even occurred.
Summary:
*Currently time is entered simply as ####. I entered 3:27pm as 1527.
*Trying to reformat the time column results in 0000 in all cells in the column that previously had a ####.
*Modifying the 0000 displays as 6/13/1906 12:00:00 AM
*I want to format the time as hhmm so I can simply type in 2357, and have it display as 2357, but understand I mean 11:57pm, and let me take averages.
*Hell, even being able to enter 1547 and have it auto format to 15:47 or 3:47p would be great.
Thanks for reading my question!
An easy way to apply an autoformat (though Excel won't see it as a true "Time") is to go into Format Cells>Custom> and use ##":"##. This will turn 1245 into 12:45. Mind you, this will be a text string so if you copy it to another cell and then apply a time, it will show as 12:00:00. Excel will also not be able to run formulas on it, but it's a quick and dirty way to make it look pretty.
Another option is to have a formula such as =TIME(LEFT(A1,2),RIGHT(A1,2),) where A1 would be replaced with the cell you are actually referencing. This will convert the number to a time that Excel will recognize as a time allowing you to run other functions on it, but requires another column.
If you are entering the times as 4-digit numbers, you'll need to do a calculation to get the hours and minutes, then use the TIME function to get an actual time:-
=TIME(A1/100,MOD(A1,100),0)
Another way is
=LEFT(A1,2)/24+RIGHT(A1,2)/1440
but then you have to format the result as a time.
Excel sees a number like 1547 as approximately 4 years on from 1st January 1900 if you format it as a date, so it will come out as something like 26/3/1904 in UK format or 3/26/1904 in US-style format.
Note that the time function can only give you values up to 23:59:59 (stored as 0.999988426), but the second method will give you a datetime value with one or more days as the whole number part. This can be useful if you want to do calculations on times spanning more than one day.
The above behaviour is because dates and times are stored as real numbers with the whole number part representing days and the decimal part representing fractions of a day (i.e. times). In spite of misleading information from Microsoft here, dates actually start from 31/12/1899 (written as 0/1/1900) with serial number 0 and increment by 1 per day from then on.
How do I work with a Date Time -0500 value?
I have a sheet that has a value that looks like this:
2016-05-12 21:51:13 -0500
I want to be about to use it.
I want to filter all records that are greater than
2016-05-12 00:00:01 -0500
But I do not know how to work with this value.
Use this formula:
=--LEFT(A1,LEN(A1)-5)
Then format it like this
yyyy-mm-dd hh:mm:ss -\0\5\0\0
Then you can copy and paste the values and formatting where you want it
You need to convert the data into Excel date/times. With data in A1 in B1 enter:
=DATE(LEFT(A1,4),MID(A1,6,2),MID(A1,9,2))+TIME(MID(A1,12,2),MID(A1,15,2),MID(A1,18,2))
and format to display both date and time:
Let's presume for a moment that for some unknown reason Excel could not identify your string as a valid date time. You can always go back to basics and break your string down into its components. Let's start off and assume that your date time and offset string are in cell A1.
Step 1) Strip out the year
=left(A1,4)
Step 2) Strip out the month
=MID(A1,FIND("-",A1)+1,FIND("-",A1,FIND("-",A1)+1)-FIND("-",A1)-1)
That bad boy of a formula looks for the first - and the second - and based on that information finds the starting position to start pulling characters from and figures out how many characters to pull.
In your case we could have set it to pull two characters and had it start at character six as there is no variation to your date format. However, in a generic sense where there are not always leading zeros in the month, or sometimes you were flipping between four characters for the year and two characters for the year, the above would still work.
I am also assuming that month is the middle value (05) and you are not talking about December 5th here.
Step 3) Pull out the day
We could have used a similar approach using mid here, and again we could have hard coded it (wait, I did hard code two character return). Instead for a little flavour I used a right left sequence.
=RIGHT(LEFT(A1,FIND(" ",A1)-1),2)
Step 4) Pull out the time
Now you could go through the whole process and pull out hours, minutes and seconds, but Excel is usually pretty good at recognizing a time format as there is not much variation to it. Also this gives an opportunity to see a new formula for dealing with string manipulation.
Now since your time format was constant, I got a little lazy knowing that your time was always going to be eight characters long since your format always has a leading zero. As such, I used the following:
=TIMEVALUE(MID(A1,FIND(" ",A1)+1,8))
Basically, I grabbed the whole time, HH:mm:ss, and dumped it into timevalue (note there is also a datevalue). Timevalue will attempt to convert a string in time format to Excel time format as a decimal value.
Now as previously noted, if all those times are all stamped with the same -0500, just ignore it.
To get all that date and time converted into a single cell we would take each of the date parts and drop them into the DATE function and then add the time component on. In Excel speak that looks like:
=DATE(LEFT(A1,4),MID(A1,FIND("-",A1)+1,FIND("-",A1,FIND("-",A1)+1)-FIND("-",A1)-1),RIGHT(LEFT(A1,FIND(" ",A1)-1),2))+TIMEVALUE(MID(A1,FIND(" ",A1)+1,8))
Now if you want that to display with the -0500, look at Scott's answer for formatting. If you want to convert the time to local time and get rid of the -0500 then you would need to add -5 hours to the above formula which would look something like:
=DATE(LEFT(A1,4),MID(A1,FIND("-",A1)+1,FIND("-",A1,FIND("-",A1)+1)-FIND("-",A1)-1),RIGHT(LEFT(A1,FIND(" ",A1)-1),2))+TIMEVALUE(MID(A1,FIND(" ",A1)+1,8))+time(-5,0,0)
And if we were not so lazy and did not want to hard code the time, it would look more like:
=DATE(LEFT(A1,4),MID(A1,FIND("-",A1)+1,FIND("-",A1,FIND("-",A1)+1)-FIND("-",A1)-1),RIGHT(LEFT(A1,FIND(" ",A1)-1),2))+TIMEVALUE(MID(A1,FIND(" ",A1)+1,8))+TIME(LEFT(RIGHT(A1,4),2),RIGHT(A1,2),0)*IF(LEFT(RIGHT(A1,5),1)="-",-1,1)
I am trying to calculate the hour difference between two times. What I've been doing now only gives me hour indications like 1:30, 2:45, etc but I can't make diagrams based on these values. If I get 2:30 as the hour difference, it should become 2,5. if the difference is 2:45 that should be 2,75.
Change your formula to:
(B2-A1)*24
and format as General
You should just be able to subtract 1 datetime from the other. Try this:
In cell A1, enter "09/17/2012 10:00" (Excel should automatically recognize this as a date)
In cell A2, enter "09/17/2012 11:30"
In cell A3, "=(A2-A1)*24". The result is 1.5.
The problem may be that you are trying to subtract 1 'time' from another 'time' without a date component. In that case, Excel may not recognize your value as a 'time'. Try adding a dummy date to the beginning of the time.
One limitation of this is that you will get an error response of "########" if the 2nd date is earlier than the 1st (because the result is negative). If this is an issue, try "=ABS(A2-A1)*24" instead.
Have a list of dates in excel in the format (this comes originally from csv):
23/11/09 07:27:02
23/11/09 08:01:50
23/11/09 08:38:58
23/11/09 09:40:01
What I want to do is count the number of these falling between hour blocks, like 7-8, 8-9, 9-10 etc
Not sure how to get started, but one idea was just to put logic statements comparing the dates between these blocks, then adding the total "trues"
I can't get it to compare properly. When I type it the hour block marks,
e.g. 23/11/09 08:00
excel actually shows that as
23/11/2009 8:00:00 AM
and the compare doesn't work. Well actually it does the opposite of what it should.
that is:
=IF(C5>L1,IF(C5<M1,TRUE,FALSE),FALSE)
C5 being date in top codeblock, L1 and M1 being the hour blocks I manually entered in the second code block.
Has anyone got any ideas?
=hour(a1)=7
will return true if the time of the date/time value in cell A1 is between 7 and 8 (AM) and will otherwise return false.
Excel stores dates as number of days since 1900 or 1904 depending on your setting and the time as a fraction of the days. So 11:59 am 4th of July 1960 is held internally as '22101.4993055556'.
As such you cannot do plain charactrer string comparisons on dates. However ther ar lots of nifty time/date functions available to you.
You probably want :
=IF(HOUR(B1) > 8,IF(HOUR(B1)<12,"YES","NO"),"NO")
You should use Excel functions, like HOUR(), to extract the parts of the times, and apply the logic tests to those extracted values.
