ATT and DST when calling AT+CCLK?

When calling AT+CCLK? with AT+CTZU=1, the time zone is attached (format:+CCLK: "18/11/11,00:51:07-24). I am wondering how AT&T handles DST(daylight savings time).

Specifically, if I call AT+CCLK? during April in Minnesota(CST -6, DST -5). Will the CCLK return -24 (no DST, -24/4 = -6) or -20 (with DST -20/4 = -5)?

This is important for our code and how to handle using automatic time zone. We are trying to release our LTE cellular units but this is holding us up.

If anyone knows this will be a great help!

Let me ping someone that might be able to help, @ParticleD, or @mstanley are you able to assist?

This has stumped everyone. We’ve asked AT&T but haven’t heard back yet.


Was this resolved?

I tested at it looks like it does return -5 instead of -6 to account for DST.
