Hi!
How can i the argument_1 and 2 date time code change to normal date formatum? ("yyyy-MM-dd HH:mm:ss.SSS")
how can i use the SimpleDateFormat ?
where to write?

long argument_1 = 1378159200000l;
long argument_2 = LastTick.getTime();
long argument_3 = 1378159200000l;
if (argument_1< argument_2) {
}
if (!(argument_1> argument_2 && argument_1< argument_2 ) ) {
If_block_33(flow);
}
else if (argument_1== argument_2) {
}

Thank you!

use DateUtils.format, see:
https://www.dukascopy.com/wiki/#IConsole/Logging_values
Locate there the place about time formatting. If you wish to use other time formatting, see:
https://www.dukascopy.com/wiki/#Format_Date_Time

can you write a for example? please

Well, the linked wiki pages contain examples...

But if they are not clear:
For comparison just use the data as it is. Leave it long (like 1378159200000), as it can be compared.
If you want to see/check what is the 'real' date behind this millisecond value, use SimpleDateFormat:

long argument_1 = 1378159200000l;
private SimpleDateFormat sdf;
sdf = new SimpleDateFormat("yyyy-MM-dd_HHmmss");   // but the format can be whatever you prefer
sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
console.getOut().println(sdf.format(argument_1));

If you really need a complete strategy, look around on the wiki. There are plenty of examples where the SimpleDateFormat is used (for example here).

Good luck!
