280User Manual 1173.9463.02 ─ 06
If the automatism is enabled, the operating system adjusts its internal clock in autumn to
non DST and in spring to DST. The rules defining when exactly the clock must be adjusted
by which offset depend on the configured time zone, see SYSTem:TIME:DSTime:
RULE.
If the automatism is disabled, the local time is calculated as:
local time = UTC + time zone offset (no DST offset)
Parameters:
<Enable> 1: automatism enabled
0: automatism disabled
Example:
SYSTem:TIME:DSTime:MODE 1
The clock is automatically adjusted in autumn and spring.
Firmware/Software: V3.0.12
V3.0.14: support of setting (before: query only)
SYSTem:
TIME:DSTime:RULE:CATalog?
Returns all time zone values that can be set using SYSTem:TIME:DSTime:RULE.
Return values:
<TimeZoneList> Comma separated list of all supported values. Each value is rep-
resented as a string.
Usage: Query only
Firmware/Software: V3.0.14
SYSTem:TIME:DSTime:RULE <TimeZone>
Sets the time zone in the date and time settings of the operating system.
The used Daylight Saving Time (DST) rules depend on the configured time zone. So this
setting influences the automatic adjustment of the local time and date for DST. See also
SYSTem:TIME:DSTime:MODE.
Modifying the time zone modifies also the configured time zone offset, see SYSTem:
TZONe.
Parameters:
<TimeZone> Time zone as string
To query a list of all supported strings, use SYSTem:TIME:
DSTime:RULE:CATalog?.
Example:
SYSTem:TIME:DSTime:RULE "W. Europe Standard
Time"
The Western Europe time zone is set and the related DST rule set
is used.
Firmware/Software: V3.0.14
