# Time::Timezone(3pm)

## NAME

Time::Timezone -- miscellaneous timezone manipulations routines

## SYNOPSIS

```
        use Time::Timezone;
        print tz2zone();
        print tz2zone($ENV{'TZ'});
        print tz2zone($ENV{'TZ'}, time());
        print tz2zone($ENV{'TZ'}, undef, $isdst);
        $offset = tz_local_offset();
        $offset = tz_offset($TZ);
```

## DESCRIPTION

This is a collection of miscellaneous timezone manipulation routines.

`tz2zone()` parses the TZ environment variable and returns a timezone string suitable for inclusion in date-like output.  It opionally takes a timezone string, a time, and a is-dst flag.

`tz_local_offset()` determins the offset from GMT time in seconds.  It only does the calculation once.

`tz_offset()` determines the offset from GMT in seconds of a specified timezone.

`tz_name()` determines the name of the timezone based on its offset
