I have a problem in my company where after daylight savings time meetings are shown an hour off in the calendar, but in the body of the meeting the time seems fine. The real problem is when after updating the meeting from it's body (just pressing save and close) the meeting is bloated by an hour.

E.g. if a meeting after daylight savings time is from 11:00 to 12:00, it's shown on the calendar  from 12:00 to 13:00, but after updating the meeting it's shown from 11:00-13:00.

This happens only on the macs in the company.

Thank you.
