F1 – Time Zone Offset
Use function F1 to display and set the time zone offset between your Standard Time zone and Universal
Time Coordinated (UTC). Refer to
“F: World Map of Time Zones:” on page 141 . 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 page 61 .
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 page 58 .
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 page 13 .
The factory setting for F1 is UTC –8:00 hours (Pacific Standard Time).
