! These are the possbile datetime strings:
! 2000-04-21T21:00:00              datetime with -, T, & delimiters
! 20000421 210000              datetime without delimiters
! This is how integer hour, min, & sec values are converted to an integer time.
! time = hour*10000+min*100+sec              datetime with -, T, & delimiters
! This is how integer year, month, & day values are converted to an integer day.
! date = year*10000+month*100+day              datetime with -, T, & delimiters
! These are datetime iterval strings:
! PnYnMnDTnHnMnSn  ! This is a fully expressed datetime interval string.
! P1D              ! This is a day-only interval string.
! PT30             ! This is a time-only interval string.
