REQ_88.1: The format of the characterstring shall be as:YYYY[-MM[-DD[Thh[:mm[:ss[.s[TZD]]]]]]]where·• YYYY: A four-digit year

The format of the characterstring shall be as:YYYY[-MM[-DD[Thh[:mm[:ss[.s[TZD]]]]]]]where·• YYYY: A four-digit year (1970 <= YYYY<=2038)• MM: A two-digit month (01 through 12 where 01=January)• DD: A two-digit day of month (01 through 31, depending on the value ofmonth and year)• hh: Two-digits of hour (00 through 23)• mm: Two-digits of minute (00 through 59)• ss: Two-digits of second (00 through 59)• s: 1 or more digits representing a decimal fraction of a second). Iffractions of a second are used, SCORM further restricts the string to amaximum of 2 digits (e.g., 34.45 - valid, 34.45454545 - not valid)• TZD: Time zone designator (Z for UTC or +hh:mm or -hh:mm).o The hh and mm shall adhere to the requirements defined abovefor hh and mm.o If the difference between local time and UTC is required then thetime can be expressed in hours and minutes (i.e., 03:10) or if thetime difference is exactly an integral number of hours, thenhours only (03).o The leading zero is required for hours less than 10.o If no TZD designator is provided then the default time zone shallbe interpreted as “local time”.o If TZD is defined, then hh:mm:ss.s shall also be defined,although they may be all zeros.At least the four-digit year must be present. If additional parts of the time areincluded, the character literals:• -• T• :• .are part of the character lexical representation.
