使用UTC时间 微秒 一行代码

f utcnow () {datetime。datetime。isoformat (): 3]) Z”

输出:

2022 - 02 - 25 - t02:08:40.684z

下面是我用来转换为XSD日期时间格式的:

from datetime import datetime
datetime.now().replace(microsecond=0).isoformat()
# You get your ISO string

我在寻找XSD日期时间格式(xs:dateTime)时遇到了这个问题。我需要从等值格式中删除微秒。

import datetime, time    
def convert_enddate_to_seconds(self, ts):
    """Takes ISO 8601 format(string) and converts into epoch time."""
     dt = datetime.datetime.strptime(ts[:-7],'%Y-%m-%dT%H:%M:%S.%f')+\
                datetime.timedelta(hours=int(ts[-5:-3]),
                minutes=int(ts[-2:]))*int(ts[-6:-5]+'1')
    seconds = time.mktime(dt.timetuple()) + dt.microsecond/1000000.0
    return seconds 

>>> import datetime, time
>>> ts = '2012-09-30T15:31:50.262-08:00'
>>> dt = datetime.datetime.strptime(ts[:-7],'%Y-%m-%dT%H:%M:%S.%f')+ datetime.timedelta(hours=int(ts[-5:-3]), minutes=int(ts[-2:]))*int(ts[-6:-5]+'1')
>>> seconds = time.mktime(dt.timetuple()) + dt.microsecond/1000000.0
>>> seconds
1348990310.26

我找到了约会时间。文件中的Isoformat。它似乎做了你想要的:

datetime.isoformat([sep])

Return a string representing the date and time in ISO 8601 format, YYYY-MM-DDTHH:MM:SS.mmmmmm or, if microsecond is 0, YYYY-MM-DDTHH:MM:SS

If utcoffset() does not return None, a 6-character string is appended, giving the UTC offset in (signed) hours and minutes: YYYY-MM-DDTHH:MM:SS.mmmmmm+HH:MM or, if microsecond is 0 YYYY-MM-DDTHH:MM:SS+HH:MM

The optional argument sep (default 'T') is a one-character separator, placed between the date and time portions of the result. For example,
>>>

>>> from datetime import tzinfo, timedelta, datetime
>>> class TZ(tzinfo):
...     def utcoffset(self, dt): return timedelta(minutes=-399)
...
>>> datetime(2002, 12, 25, tzinfo=TZ()).isoformat(' ')
'2002-12-25 00:00:00-06:39'

我开发了这个函数:

def iso_8601_format(dt):
    """YYYY-MM-DDThh:mm:ssTZD (1997-07-16T19:20:30-03:00)"""

    if dt is None:
        return ""

    fmt_datetime = dt.strftime('%Y-%m-%dT%H:%M:%S')
    tz = dt.utcoffset()
    if tz is None:
        fmt_timezone = "+00:00"
    else:
        fmt_timezone = str.format('{0:+06.2f}', float(tz.total_seconds() / 3600))

    return fmt_datetime + fmt_timezone
