Given the following datetime:
d = datetime.datetime(2018, 10, 9, 8, 19, 16, 999578, tzinfo=dateutil.tz.tzoffset(None, 7200))
d.isoformat() results in the string:
'2018-10-09T08:19:16.999578+02:00'
How can I get a string with milliseconds instead of microseconds:
'2018-10-09T08:19:16.999+02:00'
strftime() will not work here: %z returns 0200 istead of 02:00 and has only %f to get microseconds, there is no placeholder for milliseconds.
If timezone without colon is ok, you can use
d = datetime.datetime(2018, 10, 9, 8, 19, 16, 999578,
tzinfo=dateutil.tz.tzoffset(None, 7200))
s = d.strftime('%Y-%m-%dT%H:%M:%S.%f')[:-3] + d.strftime('%z')
# '2018-10-09T08:19:16.999+0200'
For colon, you need to split the timezone and add it there yourself. %z does not produce Z either for UTC.
And Python 3.6 supports timespec='milliseconds' so you should shim this:
try:
datetime.datetime.now().isoformat(timespec='milliseconds')
def milliseconds_timestamp(d):
return d.isoformat(timespec='milliseconds')
except TypeError:
def milliseconds_timestamp(d):
z = d.strftime('%z')
z = z[:3] + ':' + z[3:]
return d.strftime('%Y-%m-%dT%H:%M:%S.%f')[:-3] + z
Given the latter definition in Python 3.6,
>>> milliseconds_timestamp(d) == d.isoformat(timespec='milliseconds')
True
with
>>> milliseconds_timestamp(d)
'2018-10-09T08:19:16.999+02:00'
on 3.10 (maybe earlier, too), you can do it on a one-liner
>>> now = datetime.datetime.now()
>>> tz = datetime.timezone(datetime.timedelta(hours=-6), name="CST")
>>> now_tz = now.replace(tzinfo=tz)
>>> now_tz.isoformat("#","milliseconds")
'2023-03-02#11:02:07.592-06:00'
import datetime
now = datetime.datetime.now()
tz = datetime.timezone(datetime.timedelta(hours=-6), name="CST")
now_tz = now.replace(tzinfo=tz)
now_tz.isoformat("#", "milliseconds")
str.format(), if you can get microseconds & millisecs from datetime object you can format the strings representations in any waystr.formatcan do.strftime()is exactly the provided method for that.
