We entered the talks for the Dutch PHP Conference and the Dutch Mobile Conference a while ago, and now all the talk times seem to be off by one hour.
Says here Lorna's tutorial on webservices is at 8.30, while we originally entered it as 9.30. Same goes for all other talks.
I think that maybe daylight savings time might have something to do with it? If the talks are entered during daylight savings time (in the winter) but the event itself is outside daylight savings time (in the summer), could it be that all times are off by 1 hour when daylight savings time ends?
