I'm writing some custom reports and I just need to understand the date fields so that I can manipulate them. 

 

When I look at a date such as WorkOrder > CREATEDTIME the field shows as a number field with numbers like 1,278,473,558,292.  I'm not sure how that relates to a date and how to then convert that into an actual date. 

 

Can anyone advise?  I'm using Crystal Reports.
