parseTime regex fix for special characters

[elzoiddy]

Hi,

I made a small fix that escapes regex special characters like |()[]+?... in the time separator. It's unlikely that anyone would use any separator other than " " for their time format. But if they do and they use one of the special regex characters, they won't get a "NaN" parse error.

Also, it just happens to make the regex a little simpler by matching from the end of string and ignoring the date portion in the beginning.

Let me know what you think of this patch.

Thanks

Hey elzoiddy,

This looks like its in the right direction. But you left out the part for '.{' + dp_dateFormat.length + ',}' as this is a placeholder for the date. I will make that small tweak and commit. Also I will be adding this to dev, not the master branch.

Thanks!!
