Convert a python UTC datetime to a local datetime using only python standard library?
Date : March 29 2020, 07:55 AM
will help you I think I figured it out: computes number of seconds since epoch, then converts to a local timzeone using time.localtime, and then converts the time struct back into a datetime... EPOCH_DATETIME = datetime.datetime(1970,1,1)
SECONDS_PER_DAY = 24*60*60
def utc_to_local_datetime( utc_datetime ):
delta = utc_datetime - EPOCH_DATETIME
utc_epoch = SECONDS_PER_DAY * delta.days + delta.seconds
time_struct = time.localtime( utc_epoch )
dt_args = time_struct[:6] + (delta.microseconds,)
return datetime.datetime( *dt_args )
>>> utc_to_local_datetime( datetime.datetime(2010, 6, 6, 17, 29, 7, 730000) )
datetime.datetime(2010, 6, 6, 19, 29, 7, 730000)
>>> utc_to_local_datetime( datetime.datetime(2010, 12, 6, 17, 29, 7, 730000) )
datetime.datetime(2010, 12, 6, 18, 29, 7, 730000)

How do I convert a datetime.date object into datetime.datetime in python?
Date : March 29 2020, 07:55 AM
help you fix your problem Use the datetime.combine method with an empty time instance: dateobject = datetime.date.today()
datetime.datetime.combine(dateobject, datetime.time())
datetime.datetime.combine(dateobject, datetime.time.min)

Why method now in Python is obtained as datetime.datetime.now instead of datetime.time.now?
Date : March 29 2020, 07:55 AM
it fixes the issue "Now" is a point in time. That means date matters; if it's noon now, yesterday noon is not also now. (Time of day also matters; 9 AM today is also not now.) Thus, it makes sense to have a datetime.datetime.now, but not a datetime.time.now. It could make sense to have a datetime.time.currentlocaltime or datetime.time.currentutctime, but those methods don't exist. You could put in a feature request if you want.

dateNow = datetime.datetime.now() causes AttributeError: type object 'datetime.datetime' has no attribute 'datetime'&quo
Date : March 29 2020, 07:55 AM
wish helps you datetime.datetime.now() refers to a method (now) of a class (2nd datetime) of a library (1st datetime), however you didn't import the entire library, just the single class (from datetime import datetime). Either import the entire library or call on the class without referring to the library.

python: convert pywintyptes.datetime to datetime.datetime
Tag : python , By : user161314
Date : March 29 2020, 07:55 AM
I think the issue was by ths following , So the problem is the +00:00 timezone offset. Looking into this there's not an out of the box solution for Pythondatetime.datetime.strptime("2016-04-01 17:29:25+00:00", '%Y-%m-%d %H:%M:%S %z')
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/_strptime.py", line 324, in _strptime
(bad_directive, format))
ValueError: 'z' is a bad directive in format '%Y-%m-%d %H:%M:%S %z'
datetime.datetime.strptime("2016-04-01 17:29:25+00:00".rstrip("+00:00"), '%Y-%m-%d %H:%M:%S')
datetime.datetime(2016, 4, 1, 17, 29, 25)
pip install python-dateutil
>>> import dateutil.parser
>>> dateutil.parser.parse("2016-04-01 17:29:25+00:00")
datetime.datetime(2016, 4, 1, 17, 29, 25, tzinfo=tzutc())
