milliseconds from Unix origin time (i.e. Jan 1, 1970 0:00:00 UTC)
GeneralizedTime string (ex. 20170412235959.384Z)
This function converts from milliseconds of Unix origin time (ex. 1199145599000 for 31 Dec 2007 23:59:59 GMT) to GeneralizedTime string (i.e. YYYYMMDDHHmmSSZ). The result string may have a fraction of second.
