java - How to calculate 1 month ago in milliseconds? -


i want calculate 1 month ago current time in milliseconds. example if date 25.11.2016 want 25.10.2016 milliseconds format. how can calculate date milliseconds? below code not working think.

system.currenttimemillis() - 1000*60*60*24*30

you can use way:

calendar c = calendar.getinstance(timezone.gettimezone("utc")); c.add(calendar.month, -1); long result = c.gettimeinmillis();

note system.currenttimemillis() using utc, need create instance of calendar using same timezone.
