If some variation of that sleazy hack doesn't work and you can't
find some some source for the info you want (maybe something like
https://isDSTactiveInMyTimezone.com/ :) then you'll have to determine
if DST is active on your own.
That requires a timezone file for your locale and some source of "current
UTC time"; your system clock chip can presumably supply the latter.
Here's hoping you can find existing code (like a Python library) to
paddle around in timezone files.
If not, you can dump a timezone file with zdump; the output shows (among
other things) the exact dates/times of transitions into and out of DST,
as well as your locale's offset from UTC after each transition.
The timezone files typically live in /usr/{share,lib}/zoneinfo/
The timezone file governing your system is specified in /etc/timezone
So, on my Ubuntu system this command dumps the current timezone file:
zdump -v /usr/share/zoneinfo/$(cat /etc/timezone)
...in a text format that could be parsed to discover if DST is in effect
in my timezone. Ick.
