It optionally takes a timezone string, a time, and a is\-dst flag. .PP \&\f(CWtz_local_offset()\fR determines the offset from GMT time in seconds. It only does the calculation once. .PP \&\f(CWtz_offset()\fR determines the offset from GMT in seconds of a specified timezone. .PP \&\f(CWtz_name()\fR determines the name of the timezone based on its offset .SH NAME Time::Zone \-\- miscellaneous timezone manipulations routines .SH AUTHORS .IX Header "AUTHORS" Graham Barr David Muir Sharnoff Paul Foley .SH AUTHOR .IX Header "AUTHOR" Graham .SH "COPYRIGHT AND LICENSE" .IX Header "COPYRIGHT AND LICENSE" This software is copyright (c) 2020 by Graham Barr. .PP This is free software; you can redistribute it and/or modify it under the same terms as the Perl 5 programming language system itself.
