issue converting date to a spacific format

Good Morning group,

I am having a issue with custom formatting see below. Each month I bring a csv file inn with 500-600 items I have created a template to import it to however i need the date format changed as described below. Any HELP is greatly appreciated.
Thanks

What I would like to have is "YYYY-MM-DDThh:mm:ss-GMT" or the actually to show this: 2014-01-06T00:00:00-05:00,
however when I apply it to the cells with the date in it I get this:"2013-01-10T00:00:00-1T". I am applying it to a cell that has "10-Jan-13" in it.

Nope but thanks anyway. I am trying to get it to put the (utc -05:00) at the end and have it change to what ever zone the sheet is used in.
