I have one user with a Lenovo R400 and for the weeks starting March 13th &
20th, his appointments for those weeks are (when viewed with the that PC
using the GW client) are one hour early. ONLY that two week period, all
appointment before the March 13are correct, all after the 26th are correct

In webaccess, those appointment are correct. Same thing on his iPhone using
Mobility, appointment are correct, he logs into another computer and they
are correct. His admin assitant who has proxy access see's the hours

????? What could this be ?
