The available choices are:
UTC : Coordinated Universal Time ("temps universel coor-
donné"), also referred to as ZULU time
TAI: Temps Atomique International
GPS: The raw GPS time as transmitted by the GNSS satellites (as
of 5-August-2019, this is 18 seconds ahead of UTC time).
A local clock can be set up through the Time Management
Page; see "Local Clock(s), DST" on page149. Local timescale
allows a Local Clock to apply a time offset for Time Zone and
DST correction.
