Obviously, you can ask your computer for the current time zone like this:
PS> Get-TimeZone Id : W. Europe Standard Time DisplayName : (UTC+01:00) Amsterdam, Berlin, Bern, Rome, Stockholm, Vienna StandardName : W. Europe Standard Time DaylightName : W. Europe Daylight Time BaseUtcOffset : 01:00:00 SupportsDaylightSavingTime : True
Whether or not this information is correct, though, depends on your actual configuration. When you travel with your notebook to a different place, this won’t necessarily update your time zone.
Another way of finding out the current time zone is to call a public web service. Based on your current internet connection, it returns the time zone based on where you currently are:
PS> Invoke-RestMethod -Uri 'http://worldtimeapi.org/api/ip' abbreviation : CET client_ip : 84.183.236.178 datetime : 2021-01-04T13:31:57.398092+01:00 day_of_week : 1 day_of_year : 4 dst : False dst_from : dst_offset : 0 dst_until : raw_offset : 3600 timezone : Europe/Berlin unixtime : 1609763517 utc_datetime : 2021-01-04T12:31:57.398092+00:00 utc_offset : +01:00 week_number : 1
