#213 Random NullPointerException logged on console

[anon]

Sometimes the following gets logged:

Exception in thread "Thread-11" java.lang.NullPointerException: Cannot invoke "java.util.Date.getTime()" because "this.timeStamp" is null
    at org.cesilko.rachota.core.Task.suspendWork(Task.java:363)
    at org.cesilko.rachota.gui.DayView$1NightSwitch.run(DayView.java:1559)

So far I don't really see any adverse effect when it happens, but something important running on the background might break, I don't know.
