System time offset in DHCP option 2

[turrican64]

Hello

I have devices which use DHCP options to retrieve NTP server and Time Offset to adjust their internal clock according the Time Zone and DST when applicable. (No other method to set up these parameters in the devices.)

In pfsense in the "System/General Setup" menu this is possible to specify a location in the Timezone and pfsense is taking care to show the correct time and to apply daylight saving time if necessary.

My question is that how can configure the pfsense DHCP server to send pfsense system time offset value in the DHCP option 2?

Thank you!
