    I think it means you're timezone is set to Finland. WET -2 hours and WET -3 hours during DST.

    I'm sure someone can correct me.

    You're correct that the time zone abbreviation WET-2WET-3 generally indicates a time zone that follows Western European Time (WET) with UTC offsets of UTC - 2 during standard time and UTC - 3 during daylight saving time. 

    This specific time zone setup could be used for countries like Portugal or Spain during certain periods of the year, not just Finland, as Finland typically follows Eastern European Time (EET) with a UTC offset of UTC + 2 (or UTC + 3 during daylight saving time).

    The M3.5.0/03:00:00 and M10.5.0/04:00:00 parts indicate that DST starts on the last Sunday of March at 03:00 AM and ends on the last Sunday of October at 04:00 AM. So, during standard time, the system will follow UTC - 2 hours, and during DST, it will follow UTC - 3 hours.

    For Portugal you would want CUT0GDT,M3.5.0/1,M10.5.0/2, or WET0WEST,M3.5.0/1,M10.5.0/2.

    While WET-2WET-3 does "work" for Finland, it's supposed to be EET-2EEST,M3.5.0/3,M10.5.0/4.

    I believe "WET0WEST,M3.5.0/1,M10.5.0/2" is more effective and appropriate because WET and WEST are the standard abbreviations associated with Portugal and other countries in the WET Zone. Most time zone configurations and software libraries (like the IANA time zone database) use WET and WEST for Portugal.

    While WET-2WET-3 might technically work for Finland by applying offsets of UTC+2 (standard time) and UTC+3(daylight saving time), it is not appropriate. WET stands for Western European Time, not Eastern European Time, and is associated with countries like Portugal or the UK.
