Date and time functions

• xs:duration is underspecified so new yearMonthDuration and dayTimeDuration types are defined.

• Comparisons of Duration and Datetime Values:

  • op:duration-equal(duration $operand1, duration $operand2) => boolean

  • op:gYearMonth-equal(gYearMonth $operand1, gYearMonth $operand2) => boolean

  • op:gYear-equal(gYear $operand1, gYear $operand2) => boolean

  • op:gMonthDay-equal(gMonthDay $operand1, gMonthDay $operand2) => boolean

  • op:gMonth-equal(gMonth $operand1, gMonth $operand2) => boolean

  • op:gDay-equal(gDay $operand1, gDay $operand2) => boolean

  • op:yearMonthDuration-equal(yearMonthDuration $operand1, yearMonthDuration $operand2) => boolean

  • op:yearMonthDuration-less-than(yearMonthDuration $operand1, yearMonthDuration $operand2) => boolean

  • op:yearMonthDuration-greater-than(yearMonthDuration $operand1, yearMonthDuration $operand2) => boolean

  • op:dayTimeDuration-equal(dayTimeDuration $operand1, dayTimeDuration $operand2) => boolean

  • op:dayTimeDuration-less-than(dayTimeDuration $operand1, dayTimeDuration $operand2) => boolean

  • op:dayTimeDuration-greater-than(dayTimeDuration $operand1, dayTimeDuration $operand2) => boolean

  • op:dateTime-equal(dateTime $operand1, dateTime $operand2) => boolean

  • op:dateTime-less-than(dateTime $operand1, dateTime $operand2) => boolean

  • op:dateTime-greater-than(dateTime $operand1, dateTime $operand2) => boolean

  • op:time-equal(time $operand1, time $operand2) => boolean

  • op:time-less-than(time $operand1, time $operand2) => boolean

  • op:time-greater-than(time $operand1, time $operand2) => boolean

  • op:date-equal(date $operand1, date $operand2) => boolean

  • op:date-less-than(date $operand1, date $operand2) => boolean

  • op:date-greater-than(date $operand1, date $operand2) => boolean
