Subject: Add timezone configuration
X-Git-Tag: cgi-1.0~4^2
X-Git-Url: https://git.ucc.asn.au/?p=frenchie%2Ficalparse.git;a=commitdiff_plain;h=6913e5571252b2ebdaec7f21cf139f17cde24119;hp=5d10b2313ec7bc271d7b8bc94ca8613e2de78d62

Add timezone configuration

- Change the way calendars with no timezone information are processed
- By default process calendars as if they're Australia/Perth. This differs from the config in the rules file.
- Can now specify other timezones on the command line.
