Hello Thomas! I'm looking at another SyncEvolution test failure: http://syncev.meego.com/2012-01-21-20-16_all/testing-amd64/23-memotoo/Client_Sync_eds_event_testLinkedItemsParentChild.log.html In this case, the item was sent from the right-hand side (client B) to the server and from there imported into the left-hand side (client A). On the server the time was converted from UTC into floating time. Can you remind me in which cases the Memotoo server is doing that conversion? I'm not seeing that conversion in all cases. It does not happen for: - user pohly: sc-pim-ppc -> sc-api-nat and vice-versa - user syncevolution: sc-api-A -> sc-api-B (http://syncev.meego.com/2012-01-21-20-16_all/testing-amd64/23-memotoo/Client_Sync_eds_event_testCopy.log.html) It does happen for: - user syncevolution: sc-api-B -> sc-api-A (the failure above) As far as I remember it, Memotoo always converts from UTC except in detached recurrences. So I'm more surprised about not seeing this failure in all cases than I am about seeing it failing ;-}
