I receive this error as well when using the windows tomboy application, however the app conboy on the nokia n900 seems to sync with the web okay.
Here is the windows tomboy console output: [ERROR 21:41:49.844] Synchronization failed with the following exception: String was not recognized as a valid DateTime. at System.DateTimeParse.Parse(String s, DateTimeFormatInfo dtfi, DateTimeStyles styles) at System.DateTime.Parse(String s) at Tomboy.WebSync.Api.NoteInfo.ParseJson(JsonObject jsonObj) in c:\Projects\Private\Tomboy\Tomboy\Addins\WebSyncService\Api\NoteInfo.cs:line 66 at Tomboy.WebSync.Api.UserInfo.ParseJsonNoteArray(JsonArray jsonArray) in c:\Projects\Private\Tomboy\Tomboy\Addins\WebSyncService\Api\UserInfo.cs:line 183 at Tomboy.WebSync.Api.UserInfo.ParseJsonNotes(String jsonString, Nullable`1&latestSyncRevision) in c:\Projects\Private\Tomboy\Tomboy\Addins\WebSyncService\Api\UserInfo.cs:line 172 at Tomboy.WebSync.Api.UserInfo.GetNotes(Boolean includeContent, Int32 sinceRevision, Nullable`1& latestSyncRevision) in c:\Projects\Private\Tomboy\Tomboy\Addins\WebSyncService\Api\UserInfo.cs:line 121 at Tomboy.WebSync.WebSyncServer.GetNoteUpdatesSince(Int32 revision) in c:\Projects\Private\Tomboy\Tomboy\Addins\WebSyncService\WebSyncServer.cs:line 117 at Tomboy.Sync.SyncManager.SynchronizationThread() in c:\Projects\Private\Tomboy\Tomboy\Synchronization\SyncManager.cs:line 434 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/709378 Title: Tomboy fails to sync after editing note via web: "String was not recognized as a valid DateTime." -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
