The duration datatype represents a duration of time. The lexical representation for duration is the [ISO 8601] extended format PnYn MnDTnH nMnS, where nY represents the number of years, nM the number of months, nD the number of days, 'T' is the date/time separator, nH the number of hours, nM the number of minutes and nS the number of seconds. The number of seconds can include decimal digits to arbitrary precision.


This represents a frequency of every 6 hours.

  • P = period
  • 0Y = 0 years
  • 0M = 0 month
  • 0D = 0 days
  • T = time
  • 6H = 6 hours
  • 0M = 0 minutes
  • 0S = 0 seconds
