To all calcurse/google calendar users.

[PurposeOfReason]

Wrote a perl script to convert ics files (what google calendar exports as) to UTC time. Still has absolute paths and I mean to write a cron job to download and import it every <time here> but I have to get to work.

UPDATED

You say Calcurse the NCurses program?
i dont understand, maybe a Pic (?)

[PurposeOfReason]

when you export a calendar from google, or any program that supports timezones in the .ics file, the format is such that it calculates what time to show on the fly. Calcurse doesn't understand timezones so the imported times are wrong. Running this on the .ics before importation fixes this.

[PurposeOfReason]

Went ahead and made a github account; been meaning to for a while. If some people could test it out it would be great. Just added full date support but even if the file reads:

BEGIN:VEVENT
DTSTART:20090401
DTSTAMP:20100322T193608Z

TRANSP:OPAQUE
END:VEVENT
END:VCALENDAR

it still shows up on the 31st of March, a day early. That is true for all full day events. Even when calcurse exports it looks proper but is read wrong.
