Model 2651A High Power System SourceMeter® Instrument Reference Manual

Details
The time zone is only used when converting between local time and UTC time when using the
os.time()
and
os.date()
functions.
If only one parameter is given, the same time offset is used throughout the year. If four parameters are given,
time is adjusted twice during the year for daylight savings time.
offset
and
dstOffset
are strings of the form
"[+|-]hh[:mm[:ss]]"
that indicate how much time must be
added to the local time to get UTC time:
hh
is a number between 0 and 23 that represents hours;
mm
is a number
between 0 and 59 that represents minutes;
ss
is a number between 0 and 59 that represents seconds. The
minutes and seconds fields are optional.
The UTC-5 time zone would be specified with the string
"5"
because UTC-5 is 5 hours behind UTC and one
must add 5 hours to the local time to get UTC time. The time zone UTC4 would be specified as
"-4"
because
UTC4 is 4 hours ahead of UTC and 4 hours must be subtracted from the local time to get UTC.
dstStart
and
dstEnd
are strings of the form
"MM.w.dw/hh[:mm[:ss]]"
that indicate when daylight savings
time begins and ends respectively:
MM
is a number between 1 and 12 that represents the month;
w
is a number
between 1 and 5 that represents the week within the month;
dw
is a number between 0 and 6 that represents the
day of the week (where 0 is Sunday). The rest of the fields represent the time of day that the change takes effect:
hh
represents hours;
mm
represents minutes;
ss
represents seconds. The minutes and seconds fields are
optional. The week of the month and day of the week fields are not specific dates.
Example
settimezone("8", "1", "3.3.0/02", "11.2.0/02")
settimezone(offset)
Sets
offset
to equal +8 hours, +1
hour for DST, starts on Mar 14 at 2:00
a.m, ends on Nov 7 at 2:00 a.m.
Sets local time zone to
offset
.
