- 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.
- 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.
- 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.
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:
That means it is timezone naive, so you can’t use it with
you can give it a timezone like this
now you can change timezones
To get the current time in a given timezone, you could pass tzinfo to
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.
Note that for Python 3.2 onwards, the
datetime module contains
datetime.timezone. The documentation for
An aware current UTC datetime can be obtained by calling datetime.now(timezone.utc).
datetime.utcnow() doesn’t set
tzinfo to indicate that it is UTC, but
datetime.now(datetime.timezone.utc) does return UTC time with
So you can do:
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
To use it, to get the current time as an aware datetime object:
datetime.timezone.utc in Python 3.2+:
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
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.

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
Unix time / POSIX time / Epoch time:
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
With Pyhon 3.4, we can directly get timestamp from UTC.
To convert Unix timestamp to UTC we can use
To convert UTC time object to Unix time, we can use
Alternatively, we can use
