How about System currentTimeMillis     From the JavaDoc   Returns  the difference  measured in milliseconds  between the current time and midnight  January 1  1970 UTC  Java 8 introduces the java time framework  particularly the Instant class which     models a     point on the time-line       long now   Instant now   toEpochMilli      Returns  the number of milliseconds since the epoch of 1970-01-01T00 00 00Z -- i e  pretty much the same as above  -   Cheers
