Issue2736 This issue tracker has been migrated to GitHub , and is currently read-only. (I have portability concerns). Example: So, the idea is to subtract 1st January, 1970, 00:00:00 UTC datetime from the given datetime and by using total_seconds() method with the result. I was having similar issues with mktime. (I have portability concerns). vnice kudos, This 'works', but note the question stated: "I have a time in UTC" This method will always use the system's local timezone. Does substituting electrons with muons change the atomic shell configuration? After being plotted, the format of the x-axis can be converted to struct_time to look more appropriate for time data: This example was done using UTC as opposed to the local time (MSK), which explains why the graph starts at 3pm when kickoff in Moscow (UTC+3) was actually 6pm. For Python, the epoch time starts at 00:00:00 UTC on 1 January 1970. Usually, if you tell a computer to interpret a number as a time or date it will assume that the number in question represents the number of seconds after this epoch: Note that this system ignores leap seconds, ie it assumes there are exactly 86,400 seconds in a day (60 60 24). Why is it "Gaudeamus igitur, *iuvenes dum* sumus!" Thanks for contributing an answer to Stack Overflow! and is currently read-only. Turns out there is some missing data in some of the records. It returns time in seconds, which can be easily converted into milliseconds, as shown below: 1 2 3 4 5 6 7 import time if __name__ == '__main__': millisec = time.time() * 1000 print(millisec) Download Run Code If possible avoiding to import other libraries unless standard. Be the first to rate this post. time.mktime(randomDateTime.timetuple()) + randomDateTime.microsecond * 1e-6. The data is indexed so that comparing tuple times is intuitive. In Python, there are five main formats that time data can be in and these five formats are provided by two different built-in modules: time and datetime: There are other objects that can be relevant when working with time (eg datetime.timedelta objects which represent a change in time) but the five listed above are the main ones for representing timestamps (ie standalone moments in time). Korbanot only at Beis Hamikdash ? Why does bunched up aluminum foil become so extremely hard to compress? 1) This assumes you want to convert now, not a random datetime object. 4 Newer Python 3.3+ has datetime.datetime.timestamp (datetime.datetime.utcnow ()) Fortunately, you can provide your own format constructed using the directives to represent time and date elements as a positional argument. Aware and Naive Objects Date and time objects may be categorized as "aware" or "naive" depending on whether or not they include timezone information.

Already have an account? @J.F.Sebastian well perhaps the answer is a bit too simplistic; but what if one adds TZ handling? Do this. @Abe Indeed you were right. Specifically, So this becomes possible (as well as the methods below), I see that you are on master (and 0.13 is coming out very shortly), However - I would not recommend doing regular old addition of a fixed time difference to change timezones - because from one week to the next the timezone difference between GMT; EST; IST changes (daylight savings etc). Why does the bool tool remove entire object? The consent submitted will only be used for data processing originating from this website. Perfect Jeff, thank you! It is the number of seconds since 1st January, 1970 00:00:00 UTC.if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'codevscolor_com-medrectangle-3','ezslot_10',152,'0','0'])};__ez_fad_position('div-gpt-ad-codevscolor_com-medrectangle-3-0');if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[320,50],'codevscolor_com-medrectangle-3','ezslot_11',152,'0','1'])};__ez_fad_position('div-gpt-ad-codevscolor_com-medrectangle-3-0_1');.medrectangle-3-multi-152{border:none!important;display:block!important;float:none!important;line-height:0;margin-bottom:7px!important;margin-left:auto!important;margin-right:auto!important;margin-top:7px!important;max-width:100%!important;min-height:50px;padding:0;text-align:center!important}. Why does it fail in that case? In Python, there are six main 'formats' that date and time data can be in and these six formats are provided by two different built-in modules: timeand datetime: The timemodule can be used when working with: Unix time (seconds since the Unix epoch) struct_timeobjects (or 'structs') The datetimemodule can be used when working with: timeobjects You can construct ISO 8601 with the following: You can revert the construction with the following: The problem with this, though, is that if the string isn't formatted exactly like that, it won't be read. (Python 3.7.3 64-bit Anaconda3), 1) This assumes you want to convert now, not a random datetime object. Converting to UNIX time, what am I doing wrong here?

It is the number of seconds since 1st January, 1970 00:00:00 UTC. Use the timestamp() method to convert a datetime object to Unix time (Epoch time). Thanks for contributing an answer to Stack Overflow! python-rfc3339 (announcement) is an RFC 3339 parser. 559 It appears to me that the simplest way to do this is import datetime epoch = datetime.datetime.utcfromtimestamp (0) def unix_time_millis (dt): return (dt - epoch).total_seconds () * 1000.0 Share One method of getting stuct_time objects into a more user-friendly format is the asctime() function which represents the object as a C time: Note that if you dont specify any argument with the asctime() function it will default to using the current time: Unfortunately, the C time format used by asctime() is fixed. This is known as the Unix epoch. By using our site, you so assuming you have numpy >= 1.7. If I instead want the current UTC time (ie with no daylight sayings or time zone offsets) I can use the gmtime() function to get Greenwich Mean Time: Of course, while the above representation of time and date is informative its not very readable. emitted by date.isoformat() and datetime.isoformat(). If you want to convert a python datetime to seconds since epoch you could do it explicitly: >>> (datetime.datetime ( 2012,04,01, 0, 0) - datetime.datetime ( 1970,1,1 )).total_seconds () 1333238400.0 In Python 3.3+ you can use timestamp () instead: >>> datetime.datetime ( 2012,4,1, 0, 0 ).timestamp () 1333234800.0 This is an unusual format because the year is at the end and you have to specify the day of the week at the front. In Python, most of the functionality for working with Unix time is contained within the time module, so lets start by importing that: You can then get the current Unix time by using the time() function: One method of getting a time stamp into a more readable format is the ctime() function which converts a Unix time (ie a number) into a string using the format defined in the C programming language: If you dont include an argument, ctime() will default to using the current time: The above two examples show the time in C time format (a reference to the C programming language) which is a bit odd.
