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 193. F1 is the basis for 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 65.

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 63.

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 “3: Installation and Set-up” on 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:

F= ASCII character F

01 = function number

<S>	= ASCII space character (one or more)
<SIGN>	=	either no character or + for positive offsets or – for negative offsets
<HH>	=	one – or two-digit hours offset from 00 to12 hours

:= ASCII character for a colon

<MM>	=	two-digit minutes offset
<CR>	=	carriage return character
<LF>	=	line feed character

For example, to set the time zone offset, enter:

F1 –8:00<CR>
