Set Date & Time

[amarinelli-1994]

I have a device based on ESP32 with internal RTC as PD.
I want to set Date & Time with my CP.

The CMD_TDSET | 0x6D | Time and Date Set is deprecated and not implemented.

The OSDP documentation suggests to use TEXT command to set date & time with the format “GeneralizedTime” as defined in ISO 8601

Unfortunatelly, when I update the RTC, the new time is far from the last timestamp saved by PD and this generate an offline behavious of the PD.

There is a better method to update the RTC pd time?
Thanks,
Andrea

Hi @amarinelli-1994 Sorry for the late response.

"The OSDP documentation suggests to use TEXT command to set date & time with the format “GeneralizedTime” as defined in ISO 8601"

I don't know where you are seeing this. Can you point me to that doc? I am not familiar with any OSDP way of setting the time other than the deprecated TDSET command. But since you mentioned you are on an ESP32, can't you just use NTP to sync your wall clock?

Also, using text command to set date and time is a hack. Is your PD implementing that feature? If you are implementing that feature, then the RTC not being updated is bug in your implementation?

at a meeting last week in Austin the timestamp was put back into the specification, I will share the text as soon as final but yes follow 8601, it did exist in an earlier version.

Hi @IDmachines Thanks for the update. In that case, I will expose the public API now (since I'm planning a major release) and then finalize the wire format when a new revsion of the spec comes out.
