Convert elapsed real time to Date

问题

I'm writing a simple app to monitor sync activities on Android and am stuck with SyncInfo.startTime which returns a value based on SystemClock.elapsedRealTime(). How do I convert this value to a regular Date object?

回答1:

Found a solution to the problem:

new Date(System.currentTimeMillis() 
       - SystemClock.elapsedRealtime()
       + elapsedTime);

where elapsedTime is the time I receive from Android. As far as I've tested, this seems to return the correct date/time for an elapsed time. I'm just not very fond of this answer because Google warns not to use System.currentTimeMillis(). Unless someone has a better answer, I'm closing this question as answered.
