I've hit a brick wall.
I'm downloading encrypted level data from a server (made with a level creator I've created).
The level data stores the last updated version of the data with a long using Java.
Now to update levels, I download a list of available levels with the time they were last modified on file using php.
Many would say I'd have to store the time somewhere else, like json. Tis not an option.
I get the following results:
Fri May 08 23:05:24 CEST 2015 | timeStampJava: 1431119124273
Sat Jan 17 14:31:58 CET 1970 | fileTimeStampPHP(filemtime): 1431118989

I'm trying to compare the two using:
if(serverLevelInfo.last_updated > localLevelStorage.getLastUpdated())
Problem is if I downcast i.e
phpTimeStamp > (int)javaTimeStamp
It produces totally inaccurate results.
What does one do now?
Edit 1
Attempted suggestion:
//TODO Problem PHP int timestamp to java long timestamp.
PolyUtils.log((long)(serverLevelInfo.last_updated * 1000));
PolyUtils.log(localLevelStorage.getLastUpdated());
PolyUtils.log("---");
Result (wrong)

Unfortunately the only solution is that you have to lose some accuracy on the JAVA long. This is because PHP cannot produce longs (32bit scalar vars.)
if(serverLevelInfo.last_updated > (int)(localLevelStorage.getLastUpdated() / 1000))
Make sure that you cast int AFTER you've taken length off the long otherwise you'll be inaccuracies.
