    Default ics/ical in utc, not showing up as right local time

    Hi all,

    quick question:

    There is an ical feed which you can get from here:

    http://loco.ubuntu.com/teams/ubuntu-au/ical

    The problem is that the times are in UTC, when I import the calendar the times show up at the UTC suggested time.

    I want them to be converted to my local time, how would I best go about this?

    thanks

    Ikt,

    I download your link and the file is indeed in the suggested UTC time. I was unable to change the time of the calendar been after i made sure Zimbra was calibrated to my time zone. I did manage to find a work around. i imported the calender into Outlook then exported out as a .csv. then imported back into Zimbra.

    Hope this helps.

    Sounds good, there's no option of outlook here but I might be able to do that with evolution.

    To fix this issue should I report a bug?

    I think the problem is in the .ics feed. If I get an .ics feed from Zimbra, using

    http://zimbra.company.com/home/addre...m/calendar.ics

    It has a timezone section before the VEVENTS. E.g. in mine it appears as

    Code:
    BEGIN:VTIMEZONE
    TZID:America/New_York
    BEGIN:STANDARD
    DTSTART:19710101T020000
    TZOFFSETTO:-0500

    Individual events on my calendar contain the timezone in their date information, e.g.
    Code:
    DTSTART;TZID="America/Los_Angeles":20110413T133000
    DTEND;TZID="America/Los_Angeles":20110413T140000

    The .ics feed that you linked is missing this information, so there's no way to convert--the "native" time zone of the calendar events is unknown.

    See also iCalendar spec: 4.6.5 Time Zone Component, etc.

    That said, I suppose you could file an RFE in bugzilla to allow the user to specify the time zone of an imported calendar.
