Try this

myDate.setDate(myDate.getDate() + 1);
alert(myDate);

I have a column of timestamp converted to human readable form.
I have tried to sort it from epochtime as well as after converting. It's giving me
Fri, 08 Feb 2019 17:24:16 IST
Mon, 11 Feb 2019 02:19:40 IST
Sat, 09 Feb 2019 00:22:43 IST
which is not sorted.
I have used sort_values()
each_tracker_df = each_tracker_df.sort_values(["timestamp"],ascending=True)
why it isn't working??
Since all the time is in IST. Replace the string IST with NULL.
>>import datetime
>>times=['Fri, 10 Feb 2010 17:24:16','Fri, 11 Feb 2010 17:24:16','Fri, 11 Feb 2019 17:24:16']
>>change_format=[]
>> for time in times:
change_format.append(datetime.datetime.strptime(time, '%a, %d %b %Y %H:%M:%S'))
>>change_format.sort()
is there any way to convert date string Tue Feb 23 2016 20:11:42 GMT+0200 (EET) to timestamp in nodejs?
I was trying to use moment.js with this:
moment('Tue Feb 23 2016 20:11:42 GMT+0200 (EET)', 'YYYY-MM-DD HH:mm:ss').valueOf()
but it returned NaN to me. Maybe its impossible?
There's no need for moment.js
var d = new Date("Tue Feb 23 2016 20:11:42 GMT+0200 (EET)");
var timeStamp = d.getTime();
Another way to do it with moment, but a little unnecessary is:
moment(Date.parse('Tue Feb 23 2016 20:11:42 GMT+0200 (EET)')).format('YYYY-MM-DD HH:mm:ss');
change format with any other format you may desire.
In chrome's console:
(new Date(Date.now())).toLocaleString() returns "9/5/2014 9:43:08 PM"
new Date(Date.now()) returns 'Fri Sep 05 2014 21:43:08 GMT+0530 (IST)'
In node.js REPL/app:
(new Date(Date.now())).toLocaleString() returns 'Fri Sep 05 2014 21:43:18 GMT+0530 (IST)' which is the same as running new Date(Date.now())
What is the change I need to do to get the same output format as chrome.
I've got a date string as such:
Tue Jul 29 2014 23:44:06 GMT+0000 (UTC)
How can I add two hours to this?
So I get:
Tue Jul 29 2014 01:44:06 GMT+0000 (UTC)
Here's one solution:
var date = new Date('Tue Jul 29 2014 23:44:06 GMT+0000 (UTC)').getTime();
date += (2 * 60 * 60 * 1000);
console.log(new Date(date).toUTCString());
// displays: Wed, 30 Jul 2014 01:44:06 GMT
Obviously once you have the (new) date object, you can format the output to your liking if the native Date functions do not give you what you need.
Using MomentJS:
var moment = require('moment');
var date1 = moment("Tue Jul 29 2014 23:44:06 GMT+0000 (UTC)");
//sets an internal flag on the moment object.
date1.utc();
console.log(date1.format("ddd MMM DD YYYY HH:mm:ss [GMT]ZZ (UTC)"));
//adds 2 hours
date1.add(2, 'h');
console.log(date1.format("ddd MMM DD YYYY HH:mm:ss [GMT]ZZ (UTC)"));
Prints out the following:
Tue Jul 29 2014 23:44:06 GMT+0000 (UTC)
Wed Jul 30 2014 01:44:06 GMT+0000 (UTC)
This works well:
const epoch = new Date('01-01-2000')
const notBeforeDate = new Date(epoch).setSeconds(notBefore)
const notAfterDate = new Date(epoch).setSeconds(notAfter)
NOTE: the setSeconds() call actually adds seconds to the current Date value, it does not reset the Date to some absolute number of seconds. This detail is poorly addressed in the documentation and causes a lot of heartache when first trying to work with Dates in JavaScript.
I am working with the tumbler API and I am using the express framework for node.js, but I have a problem using the tumblr oAuth. The problem is the difference in timezones.
How I can change my current timezone?
You can set the TZ environment variable before calling any date functions.
> process.env.TZ = 'Europe/Amsterdam'
'Europe/Amsterdam'
> d = new Date()
Wed Mar 06 2013 23:30:42 GMT+0100 (CET)
> d.toString()
'Wed Mar 06 2013 23:30:42 GMT+0100 (CET)'
> d.toUTCString()
'Wed, 06 Mar 2013 22:30:42 GMT'
