Python Datetime Now Utc

Python Datetime Now Utc
  1. If input date object is in UTC: from datetime import date utcdate = date(2008, 1, 1) timestamp = (utcdate.toordinal - date(1970, 1, 1).toordinal). 24.145600 See more details at Converting datetime.date to UTC timestamp in Python.
  2. How strftime works? In the above program,%Y,%m,%d etc. Are format codes. The strftime method takes one or more format codes as an argument and returns a formatted string based on it. We imported datetime class from the datetime module. It's because the object of datetime class can access strftime method.; The datetime object containing current date and time is stored in now variable.
  3. Args: (None) Returns: (datetime.datetime): Current datetime object example: 2018-07-24 15:47:33 ' currentdate = datetime.now(tz=pytz.UTC) if Config.DEBUG and DateAccessor.mockdatetime: secondsdelta = currentdate - DateAccessor.datetimelastaccessed DateAccessor.datetimelastaccessed = currentdate DateAccessor.mockdatetime.

Def stableutcnow: 'Returns a current datetime.utcnow that doesn't change during a request. You can use stableutcnow to make sure that timedeltas computed against utcnow in various areas of your code are consistent with each other without having to inject an explicit datetime into each one. Question or problem about Python programming: I am dealing with dates in Python and I need to convert them to UTC timestamps to be used inside Javascript. The following code does not work: d = datetime.date(2011,01,01) datetime.datetime.utcfromtimestamp(time.mktime(d.timetuple)) datetime.datetime(2010, 12, 31, 23, 0) Converting the date object first to datetime also does not help.

Question or problem about Python programming:

Why does this datetime not have any timezone info given that it is explicitly a UTC datetime?

I would expect that this would contain tzinfo.

How to solve the problem:

Solution 1:

That means it is timezone naive, so you can’t use it with datetime.astimezone

you can give it a timezone like this

Eclipse software repository

now you can change timezones

To get the current time in a given timezone, you could pass tzinfo to datetime.now() directly:

It works for any timezone including those that observe daylight saving time (DST) i.e., it works for timezones that may have different utc offsets at different times (non-fixed utc offset). Don’t use tz.localize(datetime.now()) — it may fail during end-of-DST transition when the local time is ambiguous.

Datetime

Solution 2:

Note that for Python 3.2 onwards, the datetime module contains datetime.timezone. The documentation for datetime.utcnow() says:


An aware current UTC datetime can be obtained by calling datetime.now(timezone.utc).

So, datetime.utcnow() doesn’t set tzinfo to indicate that it is UTC, but datetime.now(datetime.timezone.utc) does return UTC time withtzinfo set.

So you can do:

Solution 3:

The standard Python libraries don’t include any tzinfo classes (but see pep 431). I can only guess at the reasons. Personally I think it was a mistake not to include a tzinfo class for UTC, because that one is uncontroversial enough to have a standard implementation.

Edit: Although there’s no implementation in the library, there is one given as an example in the tzinfo documentation.

To use it, to get the current time as an aware datetime object:

There is datetime.timezone.utc in Python 3.2+:

Solution 4:

The pytz module is one option, and there is another python-dateutil, which although is also third party package, may already be available depending on your other dependencies and operating system.

I just wanted to include this methodology for reference- if you’ve already installed python-dateutil for other purposes, you can use its tzinfo instead of duplicating with pytz

Python get current time utc

I tend to agree that calls to utcnow should include the UTC timezone information. I suspect that this is not included because the native datetime library defaults to naive datetimes for cross compatibility.

Solution 5:

To add timezone information in Python 3.2+

Hope this helps!

Python Datetime Now Utc

Coordinated Universal Time(UTC):

It is the primary time standard by which the world regulates clocks and time. To get current UTC time in Python, we can use datetime module.

Unix time / POSIX time / Epoch time:

Python datetime now utc example

It is a system for describing instants in time, defined as the number of seconds that have elapsed since 00:00:00 Coordinated Universal Time (UTC), Thursday, 1 January 1970, not counting leap seconds. To get Unix timestamp, we can use time module.

With Pyhon 3.4, we can directly get timestamp from UTC.

Conversions:

Now

To convert Unix timestamp to UTC we can use utcfromtimestamp function.

To convert UTC time object to Unix time, we can use strftime function.

Alternatively, we can use calendar.timegen function.
