[Gambas-user] Daylight "saving" and time zones

[Jussi Lahtinen]

I found my answer. It's no. I just got this: "10/28/2019 02:04:23.316"

If I'm in Finland and say I have meeting tomorrow at 13:00 in London. The
assumption is that the 13:00 is time for meeting *in London*, independently
where and when I write down it to my calendar. When me and my device goes
to London the system clock is shifted so that my calendar is readable. Thus
13:00 is always correct despite of the time zone, independently where and
when it was written down.
