org.thales.punch.libraries.punchlang.operator.TryEpochOperator

public class TryEpochOperator
extends Object

Easily retrieve a timestamp from a String.

This operator tries many known patterns to find out the right one. Once found that pattern will be reused for achieving maximal performances.

 [mytimestamp] = tryEpochSec([user][date]);
 

To get it using in milliseconds use:

 [mytimestamp] = tryEpochMs([user][date]);
 

You can also provide default values as follows:

 [mytimestamp] = tryEpochSec([user][date], 0L);
