6.3.6 DATE AND TIMEZONE
Syntax: date [hh:mm:ss] [mm/dd/yyyy]
timezone NAME=<timezone> START=<start time> STOP=<stop time>
timezone help
The date command sets the system date and time. Without arguments the date command displays
the current date & time settings. Since the DT-6X60 does not have a battery backed-up timing
device, it may lose time across system reboots.
The timezone command configures the parameters for the user's time zone, for proper display of
the date and time. It is intended that time be kept internally according to "Universal Time" (formerly
known as Greenwich Mean Time). The time zone should be administered so that the date
command and all reports that might print dates (e.g. timestamps on files) can display local time
while the system uses Universal Time. The help option of timezone prints a description of how to
set the timezone (similar to the following).
The NAME parameter takes the form LBLhLBLh (for example NAME=PST8PDT7), where the first
LBL is the 3-letter label that designates "standard time" in that time zone, and the second LBL
designates "daylight savings", if any, in that time zone. The first and second "h" values designate
the number of hours west of UTC for standard and daylight savings time, respectively. These
numbers may be expressed in one of three forms:
n 'n' hours west of UTC (-n if east)
h:m 'h' hours and 'm' minutes west of UTC (-h:m)
n.m 'n.m' hours (i.e. decimal fraction) west of UTC
The given example, NAME=PST8PDT7, would be used for Pacific Standard Time with daylight
savings. When daylight savings is NOT to be used, just enter the same values for the first and
second "LBL" and "h", e.g. NAME=PST8PST8.
The START and STOP values give the date and time daylight savings starts and stops, according
to the notation: wDayMonTime, where:
Day the day of the week ('Sun', 'Wed', etc.)
Mon the month
w which such 'Day' of the month (e.g. '1' for the first, etc., and '5' denotes "last")
Time h:m is the time to switch to the new mode
The new rule that became effective in 2007 for most U.S. time zones (and the default for
START
and
STOP ) is:
START=2SunMar2:00 STOP=1SunNov2:00

which declares that daylight savings starts on the second Sunday of March at 2 AM and ends on
the first Sunday of November at 2 AM.
