On FileMaker SDK or FileMaker Go on iOS Devices,
If you edit a TimeStamp Field and use the iOS Date / Time Picker UI Object, and hit done on the top right of the touch keyboard. Your TimeStamp is missing seconds.
If later you decided to query with this value with SQL Statements, it will crash your FileMaker File.
Please see my video of the the UI Activity. Remember key piece is hitting done on keyboard immediately.
