Select the drop-down list and choose the time code source from these choices. The
default value is local (DST).
Local (DST): Uses the local time of day with Daylight Savings Time offset
as the time code.
Local (No DST): Uses the local time of day without Daylight Savings Time
offset as the time code.
UTC: Uses Coordinated Universal Time as the time code.
Program Time: Uses the program time counter as the time code.
Note: The Local (DST), Local (No DST) and UTC menu items are available only
when Option GPS is installed in the instrument.
Use this menu item to set a time code offset for the SDI outputs. This is an offset from
the selected time code source.
Note: The offset adjustment allows you to enter a time zone correction of up to
±23:59 hours. However, the ST309 standard only implements codes for time zones
in the range of -12 to +13 hours. Therefore, when you are using ST309 data as the
Time of Day source, it is recommended that the combined programmed offset from
time zone and DST be restricted to the range of -12 to +13 hours.
