[Gambas-user] Best way converting dates into strings forth and back

[Jussi Lahtinen]

Again, in different words. Here we give the date in local time and get the
output in UTC:

? Cstr(Date(2021, 12, 10, 22, 27))
12/10/2021 20:27

? Cstr(Date(2021, 12, 10, 22, 27))
12/10/2021 19:27

Depending if it is winter or summer. So, it doesn't work. The problem is in
the loss of information. IE the relevant information is not stored.

Does anyone else understand the issue?
