:SHOWCLOCK
SYSTEM TIME: FRI, JUL 24, 1987, 8:52:53 AM
CURRENT TIME CORRECTION: 0 SECONDS
TIME ZONE: 7 HOURS 0 MINUTES WESTERN HEMISPHERE
Note that in the example above the system clock was slower than normal for several
minutes. Cancelling the correction did not undo that change; it merely prevented any
further time change. Thus after this sequence of commands, the system clock is set to a
slightly earlier time than if no SETCLOCK command had been issued.
Examples of the Time Zone Form:
Moving from Standard Time to Daylight Savings Time:
The following example illustrates changing the system time zone offset from 8 hours 00
minutes in the Western Hemisphere (Pacific Standard Time) to 7 hours 00 minutes in the
Western Hemisphere (Pacific Daylight Savings Time). This command will cause local time
to jump forward immediately one hour. Universal Time will be unchanged.
:SETCLOCK TIMEZONE=W7:00
SYSTEM TIME: SUN, APR 4, 1993, 7:12:00 AM
CURRENT TIME CORRECTION: 3600 SECONDS

Moving from Daylight Savings Time to Standard Time:
The following example illustrates changing the system time zone offset from 7 hours 00
minutes in the Western Hemisphere (Pacific Daylight Savings Time) back to 8 hours 00
minutes in the Western Hemisphere (Pacific Standard Time). This command will cause
local time to slow down until it loses one hour. Users of Universal Time will see an
immediate one-hour jump forward, followed by a slowdown until system Univeral Time
again matches real Universal Time.
