5: Function Reference
F1 – Time Zone Offset
Use function F1 to display and set the time zone offset between your Standard Time zone
and Coordinated Universal Time (UTC). Refer to “F: World Map of Time Zones:” on page
202. F1 is the basis for Standard Time and Local Time used by F69. For an expanded
explanation of Local, Standard, UTC, and GPS time, see “F69 – Time Mode” on page90.
For example, to set the time zone for Pacific Standard Time (UTC –8 hours), set the value in
F1 to
–08:00. Do not include the 1-hour Daylight Saving Time (DST) offset in this value. DST is
handled separately by “F66 – Daylight Saving Time (DST) Mode” on page84.
Because the front panel display can be configured to display/distribute Local or Standard
time, we recommend configuring F1 as described in the “3: Installation/Configuration” on
page21.
The factory setting for F1 is UTC –8:00 hours (Pacific Standard Time).
