PTP may be distributed in different timescales, including the 2 common scenarios below which are of interest to TimeKeeper: TAI - the delivered time is based on the TAI timescale with an offset to be applied to transform the time to UTC. UTC - the timescale is natively in UTC and there’s no offset/correction needed. florist in topanga ca
