DATE_DIFF now accepts a new parameter, absolute, that maintains polarity on the expression when set to FALSE:

DATE_DIFF('2025-01-23T13:30:45', '2025-01-23T10:00:00', absolute: FALSE)

returns:

{
  "days" => -0.15,
  "hours" => -3.51,
  "minutes" => -210.75,
  "seconds" => -12645,
  "weeks" => -0.02,
  "units" => {
    "days" => 0,
    "hours" => -3,
    "minutes" => -30,
    "months" => 0,
    "seconds" => -45,
    "weeks" => 0,
    "years" => 0,
  },
}
