Comment 3 for bug 1223230

I created myself an account for 15 days trial and at least in that one I could reproduce this (see attachemnt). Note that when you _export_ data from openERP the dates in csv will be in UTC timezone but when you _import_ data the dates in csv has to be in your own timezone (I think this is also weird behavior but that is how it currently works) so after you have exported the data you have created aside of modifying ids you have to also change the time to correspond the times in your OpenERP attendance view because like I said OE doesn't allow importing attendances except if there is already created data which date and time are exactly same (remember also seconds).
