How do you compare two epoch Times?
Goal is to compare 2 times, 1 from android device and the other provided from database server (in epoch), http://www.epochconverter.com/ If one time is newer then the other, a value should be added (marked as new in a listview, newItem = true;).
Can you subtract epoch time?
Converting a date and time into an epoch value makes it easier to find the difference, add, and subtract from a time value. For example, you could convert the time to an epoch and subtract it from another epoch value to quickly determine the difference.
How to calculate the difference between two time stamps?
Because time stamps are represented as serial numbers, you can subtract the earlier time from the later time to get the difference. For example, if cell B3 contains 9:00:00 and cell C3 contains 17:30:00, the following formula returns 08:30:00 (a difference of eight hours and 30 minutes):
How to calculate time elapsed between two timestamps?

So all that’s needed is to convert your date/timestamp into a format that GNU date can understand, use maths to determine the difference, and output the result We’ve not provided timezone information here so it assumes local timezone.
How to find time difference between two Epoch Times?
Just subtract the difference divide by 60 to get in minutes. The epoch time is in seconds, for milliseconds just multiple by 1000 found the solution, it was so simple.

When to use ABS to calculate time stamps?
But if the work shift spans midnight, the result is a negative time. For example, you may start work at 08:00 PM, and end work at 5:00 AM the next day. Using the ABS function (to calculate the absolute value) isn’t an option in this case because it returns the wrong result (15 hours).
