need a function to sort a cdt by a date/time field. Is there such a function to

Use a!todatasubset() and specify the sort information in the a!pagingInfo()

load(
  local!data: {
    {
      id: 1,
      date: now()
    },
    {
      id: 2,
      /* now() minus 2 hrs */
      date: todatetime(now() - (2/24))
    },
    {
      id: 3,
      /* now() minus 24 hrs */
      date: todatetime(now() - (24/24))
    },
    {
      id: 4,
      /* now() minus 72 hrs (3 days) */
      date: todatetime(now() - (72/24))
    }
  },
  local!pagingInfo: a!pagingInfo(
    startIndex: 1,
    batchSize: -1,
    sort: a!sortInfo(
      field: "date",
      /* Change to true of false */
      ascending: false
    )
  ),
  local!sortedData: todatasubset(
    arrayToPage: local!data,
    pagingConfiguration: local!pagingInfo
  ).data,
  /* Show results */
  local!sortedData
)
