I just read the description of widdst, and it provides a manual interface to set the DST flag. If someone found the need to write it, it kind of suggests that getIsDST() doesn't work out of the box…?
But Android has all the relevant data, whether or not it's a bug that it doesn't share it.
So my proposal is: gadgetbridge should send not just the time and the offset, but also the DST flag, the official time zone ID, and the short code for the time zone; perhaps also the next anticipated DST transition. On the Bangle, the DST flag should be updated when it is received, all these values should be persisted as the offset is already, and an event should be sent if they changed.
