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
Standard Time and Local Time used by F69. For an expanded explanation of Local, Standard, UTC, TAI,
and GPS time, see "F69 – Time Mode" on page
For example, to set the time zone for Pacific Standard Time (UTC –8 hours), set the value in F1 to –
08:00. Exclude the 1-hour Daylight Saving Time (DST) offset from this value. DST is handled separately
by "F66 – Daylight Saving Time (DST) Mode" on page
Because the front panel display and Multicode Output card can be configured to display/distribute Local
or Standard time, we recommended configuring F1 as described in the
page 15.
The factory setting for F1 is UTC –8:00 hours (Pacific Standard Time).

Command Line
To display the time zone offset, enter "F1<CR>" on the command line. The XLi responds with the
following character string:
F1<S><SIGN><HH>:<MM><CR><LF>
where:
= ASCII character F
F
= function number
01
= ASCII space character (one or more)
<S>
<SIGN> = either no character or + for positive offsets or – for negative offsets
= one – or two-digit hours offset from 00 to12 hours
<HH>
= ASCII character for a colon
:
= two-digit minutes offset
<MM>
= carriage return character
<CR>
= line feed character
<LF>
For example, to set the time zone offset, enter:
F1 –8:00<CR>
