How do I create a Unix timestamp on Android?

Question

I want to create a URL post request with a Unix timestamp on the end of the url.

You should really try to describe your problems better. Don't leave people to guess what it is that you're really trying to achieve. — Aleks G

It's quite simple:

long timestamp = Calendar.getInstance().getTime() / 1000;

Is this as good as System.currentTimeMillis() / 1000L ? (It looks less efficient to me - unless I am missing something?)

For getting the current time, @Nesim has the better answer, but this answer is great if you already have a calendar object with a custom time. myCalendar.getTimeInMillis() / 1000

Updated answer with Kotlin:

val unix = Calendar.getInstance().timeInMillis

This answer is wrong. It should be Calendar.getInstance().timeInMillis / 1000. Check the other answers.
