W3cDateTimeUtil (Internet Time Utility 1.5.1 API)

All Known Implementing Classes:

EthloITU
```
public interface W3cDateTimeUtil
```
This class deals with the formats mentioned in W3C - NOTE-datetime: https://www.w3.org/TR/NOTE-datetime
- Year:
  YYYY (eg 1997)
- Year and month:
  YYYY-MM (eg 1997-07)
- Complete date:
  YYYY-MM-DD (eg 1997-07-16)
- Complete date plus hours and minutes:
  YYYY-MM-DDThh:mmTZD (eg 1997-07-16T19:20+01:00)
- Complete date plus hours, minutes and seconds:
  YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00)
- Complete date plus hours, minutes, seconds and a decimal fraction of a second
  YYYY-MM-DDThh:mm:ss.STZD (eg 1997-07-16T19:20:30.45+01:00)
where:
- YYYY = four-digit year
- MM = two-digit month (01=January, etc.)
- DD = two-digit day of month (01 through 31)
- hh = two digits of hour (00 through 23) (am/pm NOT allowed)
- mm = two digits of minute (00 through 59)
- ss = two digits of second (00 through 59)
- S = one or more digits representing a decimal fraction of a second
- TZD = time zone designator (Z or +hh:mm or -hh:mm)
