| Summary : tied $TZ setting %ENV and calling tzset()
|
Description :
\'Tie::TZ\' provides a tied \'$TZ\' variable which gets and sets the TZ
environment variable \'$ENV{\'TZ\'}\'. When it changes \'%ENV\', it calls
\'tzset()\' (see POSIX) if available, ensuring the C library notices the
change for subsequent \'localtime()\' etc.
$TZ = \'GMT\';
For a plain set, you can just as easily store and \'tzset()\' yourself (or
have a function do the combination). The power of a tied variable comes
when using \'local\' to have a different timezone temporarily. Any \'goto\',
\'return\', \'die\', etc, exiting the block will restore the old setting,
including a \'tzset()\' for it. See _examples/tie-tz.pl_ in the sources for
complete program.
{ local $TZ = \'GMT\';
print ctime();
}
{ local $TZ = \'GMT\';
die \'Something\';
}
Storing \'undef\' to \'$TZ\' deletes \'$ENV{\'TZ\'}\' which unsets the environment
variable. This generally means the timezone goes back to the system default
(_/etc/timezone_ or wherever).
As an optimization, if a store to \'$TZ\' is already what \'$ENV{\'TZ\'}\'
contains then \'POSIX::tzset()\' is not called. This is helpful if some of
the settings you\'re using might be the same -- just store to \'$TZ\' and it
notices when there\'s no change. If you never store anything different from
the startup value then the \'POSIX\' module is not even loaded.
If \'tzset()\' is not implemented on your system then \'Tie::TZ\' just sets the
environment variable. This is only likely on a very old or very limited C
library. Of course setting the environment variable might or might not
actually affect the timezone in force (see perlport/Time and Date).
