I need to setup an NTP server that is 1 hour ahead of the correct time. Can I sync to an NTP server w/ the correct time and then offset it? Or how can I go about this?

Thank you.

Configure it as though you are in an adjacent time zone?

yes. we have phones that pull their tz offset, which can't be changed. So an NTP server w/ the wrong time is the only option.

NTP uses UTC and any time zone correction is applied locally. A local time server would work but it could not be automatically synced to another time server.

I would not think that phones need to be accurate to the millisecond so my first thoughts would be to create a script to read the time from another time server using the rdate protocol and manually update the time via the date command.

Manually using ntpdate and then applying an offset via the date would work. If you use the server for anything else there would be the possibility of files dates and logs entries to have bad times.
