Hello ddy,
Thank you.
You are right. IE doesn't work the same as FF. Sorry, it's my fault. I will update them.

Ah well, in IE7 and previous it doesn't work that way anyway (IE8?) so if you want your code to work as expected for most people, you should use slice(-2). Incidentally, the documentation in this site for substr doesn't talk about negative indexes while the slice documentation does. I realize that the ecmascript final doc DOES talk about negative indexes for substr but apparently IE doesn't comply. To see what I mean, bring up IE and in the address bar type javascript:'abcdef'.substr(-2) and you'll get 'abcdef', not 'ef'. FF works as the current standard says. Sorry for the confusion.

No. -2 begins from the end.
'abcdefg'.substr(2) = 'cdefg'
'abcdefg'.substr(-2) = 'fg'

this should use slice(-2) rather than substr(-2) since for two digit minutes or seconds it displays 3 digits (e.g. 054:011 rather than 54:11)
