Set and print Daylight Savings Time
The daylight savings time adjustment can be programmed to take place
automatically. You can set the date to change to daylight savings, and to
return to standard time. This information can be queried at any time.
The following commands are accepted by this program for this capability.
The system clock MUST ALREADY be set for the daylight savings time to
be updated. This information survives sysload.
• FWTM = Set the date and time for the clock to move forward.
• BWTM = Set the date and time for the clock to move backward.
• SDST = Enable or disable the automatic change.
• TDST = Query the change information.
To implement these commands, use the following.
• FWTM <month> <week> <day> <hour>
month = 1-(4)-12 [January-December]
week = (1)-5, L [1st-5th, L is the last week of the
month]
day = (1)-7 [Sunday-Saturday]
hour = 1-(2)-22 [Midnight-11:00 pm]
• BWTM <month> <week> <day> <hour>
month = 1-(10)-12 [January-December]
week = (1)-5, L [1st-5th, L is the last week of the
month]
day = (1)-7 [Sunday-Saturday]
hour = 1-(2)-22 [Midnight-11:00 pm]
• SDST ON, (OFF)
ON enables the automatic change capability
OFF disables the automatic change capability
• TDST <CR>
The output reflects the input format to indicate the
change information.
