Alphito:
I'm not seeing any issues with my calendar showing times wrong (synced a number of new events during the day). Have you checked the time zone that your google calendar is set to? I presume you have it set to Buenos Aires, but just thought I should double check. Because it is a one hour offset, I would expect it to be a complication with the time zone data reported by google, and the interpretation of said information. To calculate the time, mCalendar takes the reported time (2008-10-1T12:00-4...) and just drops off the time zone correction (1008-10-1T12:00). I don't know if the web interface shows time based off of an internet clock, or the clock on your computer, but that could be part of the issue. Could you confirm what your time zone setting is, and I'll see if I can find any thing to help out.

With my correction, auto sync works perfectly for me.
