Doh! I didn't spot that the lines concatenated below! It should of
course be:
| from datetime import datetime, timedelta
from zoneinfo import ZoneInfo
# This time is after British Summer Time (BST) ends
x = datetime(2022, 10, 31, 18, 30, tzinfo=ZoneInfo("Europe/London"))
str(x)
'2022-10-31 18:30:00+00:00'
x.tzname()
'GMT'|

There seems to be multiple ways of writing the above block. In the
Python doc (https://docs.python.org/3/library/zoneinfo.html). I found:
fromzoneinfoimport ZoneInfo
fromdatetimeimport datetime, timedelta
dt = datetime(2020, 10, 31, 12, tzinfo=ZoneInfo("America/Los_Angeles"))
print(dt)
2020-10-31 12:00:00-07:00
dt.tzname()
'PDT'
I began to wonder if the date-time group 2020-10-31 12:00-07:00
referred to the end of Daylight Savings Time in LA, but that isn't
quite right because in 2020 DST ended on Sunday 1st Nov. In any case,
why would you hardwire any date into your code, so that you were
committed to the perpetual maintenance task of updating it every 12
months?
I have found a different example for GMT:
|>>> from datetime import datetime, timedelta >>> from zoneinfo import
ZoneInfo >>> >>> # This time is after British Summer Time (BST) ends
>>> x = datetime(2022, 10, 31, 18, 30,
tzinfo=ZoneInfo("Europe/London")) >>> str(x) '2022-10-31
18:30:00+00:00' >>> x.tzname() 'GMT' |
This is almost, but not quite, the same as the LA example, and nowhere
can I find a proper definition of the DTG information.
Does anyone have any experience of using this Python Module?
