Not reproduced on my computer with the latest Glances version (develop branch and 3.3.0.4):

Perhaps the issue came from the timezone... But in this case i should also have 1h of difference....

For maintainers, some issues related to the time zone: issue #1249 / #1337 / #1598

@doopler Can you provide the following information from a command line:

# python
>>> from datetime import datetime
>>> from time import tzname, strftime, mktime
>>> tzname
('CET', 'CEST')
>>> strftime('%Y-%m-%d %H:%M:%S %Z')
'2022-12-12 11:54:51 CET'
>>> datetime.fromtimestamp(mktime(datetime.now().timetuple())).strftime("%Y-%m-%d %H:%M:%S %Z")
'2022-12-12 11:54:53 '

Thanks !

@doopler can you test this issue with the latest version Glances 3.4.0.1 ?

[doopler]

yes of course. I'll keep you posted.
thanks

Create a GalncesDate method to deal with date:

Some tips:

>>> pytz.timezone('UTC')
<UTC>
>>> pytz.timezone('UTC')
<UTC>
>>> datetimepytz.timezone('UTC')
KeyboardInterrupt
>>> from datetime import datetime
>>> datetime.now()
datetime.datetime(2023, 10, 29, 10, 49, 14, 467967)
>>> datetime.now(tz=pytz.timezone('UTC'))
datetime.datetime(2023, 10, 29, 9, 50, 28, 924120, tzinfo=<UTC>)

It seems that you need to add pytz library:
pip install pytz
or
apk add py3-tz

at least for me it works.

[zuperjotmeil]

apk add py3-tz py3-tzdata py3-tzlocal
This fix it for me
