GeneralizedTime or UTCTime string (ex. 20170412235959.384Z)
seconds from Unix origin time (i.e. Jan 1, 1970 0:00:00 UTC)
This function converts from GeneralizedTime string (i.e. YYYYMMDDHHmmSSZ) or UTCTime string (i.e. YYMMDDHHmmSSZ) to seconds from Unix origin time (i.e. Jan 1 1970 0:00:00 UTC). Argument string may have fraction of seconds however result value will be omitted. As for UTCTime, if year "YY" is equal or less than 49 then it is 20YY.
