:: set the FileStamp variable to the current date:  YYMMDD_HHMMSS
:: the simplest method, to use existing TIME ad DATE variables:
:: date = Thu 09/17/2015
:: time = 11:13:15.47
::        012345678901234567890
::
:: There is no leading zero for single digit hours (e.g. 9:00am), so we need to manually include the zero
::                                                                      here  |
