The current Unix time:

DateDiff("s", "01/01/1970 00:00:00", Now())

date2epoch converts a VBScript date to an Unix timestamp:

function date2epoch(myDate)
date2epoch = DateDiff("s", "01/01/1970 00:00:00", myDate)
end function

Usage example:

date2epoch(Now())

epoch2date converts Unix timestamps back to VBScript dates:

function epoch2date(myEpoch)
epoch2date = DateAdd("s", myEpoch, "01/01/1970 00:00:00")
end function

Convert an epoch to human readable date:

var myDate = new Date( your epoch date *1000);
document.write(myDate.toGMTString()+"<br>"+myDate.toLocaleString());

var myEpoch = myDate.getTime()/1000.0;
document.write(myEpoch);

The example above gives the following output:

There are many ways to create dates in Javascript (for example with setFullYear, setMonth, setDay etc.).
