Hi,

searching on the internet and on the forum, I have not found a solution.

I used the NTP function on the PLC to synchronize the date and time (UTC).

I would like to select the use of DST (Daylight Saving Time) from runtime (same function present on HMI comfort as "SetDaylightSavingTime").

I would also like to set the timezone from runtime.
I use the SET_TIMEZONE function on PLC.
I would like to use the bias, or an index that corresponds to a specific time zone.
On PLC I use a list of timezones (even if for functional purposes SET_TIMEZONE only uses the bias):

value = 0..114

[list of timezones attached]

If the selection index is usable, is there a list of timezones for the Unified System?
