I'm using the RTC DS3234 with the 28X2 chip.
How do I know the daylight saving time? How do I program the DST to the RTC?

You have to handle DST in your program.

The best way in my opinion is to always keep the RTC running on non-DST time then add an extra hour when DST is active.

That does mean that if you need to set the time you have to always program the RTC with a non-DST time which may mean having to subtract an hour from the DST time when DST is active.

... or, how about twice a year you flip a switch labeled "DST" until the time reads correct? After all, DST is for people ... not computers.
