allow to parse a time decimal fraction in ParseTime() method

while here:
- let ParseDate() is able to parse such formats: "20081012" (without a separator)
  and without the month or day e.g: "2008" or "200810"
- let ParseTime() is able to parse a time without separators, e.g.:
  "141030", or "1410" or just "14"
- let Parse(...) method use ParseDate() and ParseTime()
  this will parse a format similar to ISO 8601
