tzsetup - set up old-style time zone information in the kernel
SYNOPSIS
/usr/etc/tzsetup
DESCRIPTION
tzsetup
attempts to find the offset from GMT and old-style Daylight Savings Time
correction type (see
gettimeofday.2
that most closely matches the default time zone for the machine, and
to pass this information to the kernel with a
settimeofday ()
call (see
gettimeofday.2
This is necessary if programs built under releases
of SunOS prior to 4.0 are to be run;
those programs get time zone information from
the kernel using
gettimeofday.
If it cannot find the offset from
GMT,
the offset is set to 0; if it
cannot find the Daylight Savings Time correction type, it is set to
DST_NONE,
indicating that no Daylight Savings Time correction is to be
performed.
DIAGNOSTICS
- tzsetup: Can't open /usr/share/lib/zoneinfo/localtime: reason
-
The time zone file for the current time zone could not be opened.
- tzsetup: Error reading /usr/lib/zoneinfo/localtime: reason
-
The time zone file for the current time zone could not be read.
- tzsetup: Two or more time zone types are equally valid -- no DST selected
-
There were two or more Daylight Savings Time correction types that
generated results that were equally close to the correct results.
None of them was selected. Programs built under versions of SunOS
prior to 4.0 may not convert dates correctly.
- tzsetup: No old-style time zone type is valid -- no DST selected
-
None of the Daylight Savings Time correction types generated results
that were in any way correct; none of them was selected.
Programs built under versions of SunOS
prior to 4.0 may not convert dates correctly.
- tzsetup: Warning: No old-style time zone type is completely valid
-
None of the Daylight Savings Time correction types generated results
that were completely correct; the best of them was selected. Programs built
under versions of SunOS prior to 4.0 may not convert dates correctly.
- tzsetup: Can't set time zone
-
tzsetup
was run by a user other than the super-user; only the super-user may
change the kernel's notion of the current time zone.
