handling of non-standard X-WR-TIMEZONE iCal property
Some calendar creators such as Google Calendar introduce the non-standard X-WR-TIMEZONE parameter to ICS calendar files to change the timezone. Strict interpretations according to RFC 5545 ignore the X-WR-TIMEZONE parameter. This causes the times of the events to differ from those which make use of X-WR-TIMEZONE. This module aims to bridge the gap by converting calendars using X-WR-TIMEZONE to a strict RFC 5545 calendars.
