Have TimelineConfig validate date parts as integers

[JoeGermuska]

Someone filed a support ticket because she was using month names. Timeline was using parseInt and ended up treating them all as January.

We should verify that month, date, and year are integers and log an error otherwise.

Is this the problem?

Basically, we should be distinguishing between an invalid input string and an empty input string?

yeah, i think instead of isNaN it could be something like

var x = TL.Util.trim(_date[DATE_PARTS[ix]]);
if (!x.match(/^\d*$/)) { //error else parse it and store it

this was made live in 3.3.9 but the issue wasn't closed
