LPS-32660 [5 MINUTES TO REVIEW] Small fix for calendar

Hey Ray,

I know this is calendar, but the root cause of the issue is fairly platform related, and is really small.

The basic problem was that the timezone got shifted in a wrong way during the calls, first the Time.getDate(Calendar) method shifted the time zone, then the date formatting shifted it again.

Now it has been consolidated to how it's being used in the portlet.

Thanks,
