How to convert long value difference of two time to seconds?
Example:
Insert Time is 2021-07-28 13:22:05.742906 -> Epoch Value 1627459467906
Update Time is 2021-07-28 13:22:17.779218 -> Epoch Value 1627459516218
Difference between Insert and Update Time is -> 1627459516218 - 1627459467906 = 48312
How to convert 48312 to seconds? [Either Manually or using code]
The epoch value is the number of milliseconds since 1/1/1970, so the difference is in milliseconds: just divide it by 1000.

I am trying to write a basic script that can read in a timestamp as a string and convert it into milliseconds. The timestamps I am working with are in minute:second.millisecond format.
from datetime import datetime
timestamp_start = '54:12.123'
MSM = '%M:%S.%f'
zero = '00:00.000'
start_sec = (datetime.strptime(timestamp_start, MSM) - datetime.strptime(zero, MSM)).total_seconds()
start_ms = start_sec * 1000
print(start_ms)
This may be a round about approach, but I am first using datetime.strptime to get a datetime object, then subtracting by 0 in order to get a timedelta object, getting the total seconds of the timedelta object, and finally multiplying by 1000 to convert to milliseconds.
The above code works fine, except for any timestamps over an hour.
The issue that I am running into- the timestamps do not have an hour counter. For example: 1 hour, 5 minutes, and 30 seconds comes in as 65:30.000. datetime.strptime cannot recognize this format, as it only allows the minutes to be between 0 and 59.
How can I convert these timestamps into a format recognizable by datetime? Should I first get the timestamp into hour:minute:second:millisecond format? Keep in mind the end goal is to convert these timestamps into milliseconds. If there is a better approach any suggestions are more than welcomed!
'54:12.123' isn't really a timestamp, but elapsed time, and there's no built-in method in Python that can deal with elapsed time with a format string like a timestamp format.
Since the format string in question is simply minutes and seconds separated by a colon, and seconds and milliseconds separated by a period, you can easily parse it with the str.split method:
def convert(msf):
minutes, seconds = msf.split(':')
seconds, milliseconds = seconds.split('.')
minutes, seconds, milliseconds = map(int, (minutes, seconds, milliseconds))
return (minutes * 60 + seconds) * 1000 + milliseconds
so that convert('54:12.123') returns:

I have a Power Query in excel linked to another file. This file has a time column. I understand that M language will not sum above 24 hours automatically without some work as it uses a datetime reference hence if I import a time of 25 hours it reverts back 2 hours to 1 hour...
In the 3rd column along in my image below using the second row as a reference, this is actually supposed to read 47:47:38. How can I get the instances where the value is above 24 hours to show the true hours?
I have tried using duration.hours(#hours()) this also does not work for some reason.
The same data from the source excel file is below also
Power Query doesn't have custom formats for how it displays data. If you have it read your data as a Duration instead of a DateTime it will display as [d].hh.mm.ss format, but still not with the total hours. Ultimately though this doesn't really matter because even when your data is formatted to display total hours in Excel, it's really being stored internally as days+hours+minutes+seconds. So how it displays in Power Query doesn't matter, as you can just use the hour formatting wherever you output the data to.
Now if you need to use the hours for a calculation between something that isn't another Duration, you can extract the hours by doing
Duration.Days([Your Hours]) * 24 + Duration.Hours([Your Hours])
Or now that I look at it, there is also a TotalHours function that gives you the hours plus mm:ss as a fractional amount of that
Duration.TotalHours([Your Hours])
Power BI doesn't handle this case very gracefully. A solution could be to convert the duration to a number to make it additive (so you can perform calculations and aggregations) and when you need to visualize it, to convert it to the desired format (HH:MM:SS).
Duration and Time are often confused. When such Excel files are read, the type of the column usually is DateTime, and date 1899-12-31 is added to the "time" part. You can change the data type of the column to be Decimal Number, but the "zero point" in Excel unfortunately is one day off (1899-12-30), so you need to subtract 1 from the result to get the actual "number of days" of the duration (i.e. 0.25 means 06:00:00).
So you must perform some conversion of the data. I would make a new column in the model to get the duration in the lowest granularity that I need (seconds in your example). In Power Query Editor add a custom column to calculate the duration in seconds (where Column1 is the name of the original duration column):
Duration in seconds = Duration.TotalSeconds([Column1] - #datetime(1899, 12, 31, 0, 0, 0))
Make sure the data type of this column is Whole Number (change it if necessary). Here 9144 seconds are calculated as 2 * 3600 + 32 * 60 + 24, or 02:32:24. Now you can calculate a sum on this column to get total duration in seconds for example. But when you visualize this column, don't do it directly, but make a measure to convert the data to the desired format. It could me made like this:
Measure Duration =
VAR duration_in_seconds = SUM(Sheet1[Duration in seconds])
VAR hours = ROUNDDOWN ( duration_in_seconds / 3600; 0 )
VAR minutes = ROUNDDOWN ( MOD ( duration_in_seconds; 3600 ) / 60; 0 )
VAR seconds = INT ( MOD ( duration_in_seconds; 60 ) )
RETURN hours & ":" & FORMAT(minutes; "00") & ":" & FORMAT(seconds; "00")
duration_in_seconds variable hold the total duration in seconds of the data in the context. From it we are calculating hours, minutes and seconds and constructing a string to represent the duration in the desired format. FORMAT is used to make sure there is a leading zero in case minutes or seconds are less than 10.
Here is how all three columns looks like when visualized:
Hope this helps!
I have a list of times in a column [Logtime]:
11:45:44PM
07:05:05PM
I'd like to create a measure that returns the total number of hours after 6:30PM. So given the above times:
5.5
0.58
HoursAfter:=[logtime] -6:30PM doesn't work.
Hour[logtime] - hour(18.5) also doesn't work
EDIT:
timevalue([logtime]) - timevalue("05:00:00") works but it returns a datetime ala
12/30/1899 5:17:16PM
I need to convert the time 5:17:16 into decimal hours i.e. 5.26, how can I do this?
There may be a slightly more elegant way, but I was able to create a calculated column that does what you want as follows,
HoursAfter = DATEDIFF(TIMEVALUE("6:30 PM"), Times[LogTime], SECOND) / 3600
This takes the time difference between 6:30 PM and your LogTime in units of seconds and then converts it to hours by dividing by 60*60 = 3600.
Edit: A simpler formula can be written as follows,
HoursAfter = 24 * (Times[LogTime] - TIMEVALUE("6:30 PM"))
(Multiply by 24 since the datetime values are stored in units of days.)
timevalue([logtime]) - timevalue("05:00:00")
How to get total time in minutes from datetime?
18/11/2013 07:31:04
The result should be: 451 min (it's 07*60 + 31).
Extract the hour and minute components of your date time with HOUR() and MINUTE() functions and combine them with this formula
=HOUR(A1)*60+MINUTE(A1)
=IF(I44<"0:01","0",IF(I44<"0:30","2:00",IF(I44<"1:00","2:30",IF(I44<"1:30","3:00",IF(I44<"2:00","3:30",IF(I44<"2:30","4:00",IF(I44<"3:00","4:30",IF(I44<"3:30","5:00",IF(I44<"4:00","5:30",IF(I44<"4:30","6:00",IF(I44<"5:00","6:30",IF(I44<"5:30","7:00",IF(I44<"6:00","7:30",IF(I44<"6:30","8:00",IF(I44<"7:00","8:30",IF(I44<"7:30","9:00",IF(I44<"8:00","9:30",IF(I44<"8:30","10:00",IF(I44<"9:00","10:30",IF(I44<"9:30","11:00",IF(I44<"10:00","11:30","")))))))))))))))))))))

I am using this function to add specific amounts of time to specific range of time and this seems like there must be a better method of doing this.
For example: for a input time of < 30 min, would output 2:00 hr, for input time of < 1:00 would output 2:30 ... and for each 30 min increment in the input the output would increment by 30 minutes
Perhaps just round down to the next half hour then add 2 hours, i.e
=IF(I44=0,0,FLOOR(I44,"0:30")+"2:00")
[with an IF to deal with zero values]
Format result cell as a time value, e.g. h:mm or similar
