Time expressions

M42PL provide a time expression syntax to select time ranges.

The general expression syntax is:

(-|+)<value><unit>@<precision>

Where:

• (-|+) indicates if you decrement (-) or increment (+) the time offset
  • By default, M42PL assumes you decrement (-)
• <value> is an integer, representing the number of <unit> to decrement or increment
• <unit> is the time unit in:
  • ms: microsecond
  • s: second
  • m: minute
  • h: hour
  • d: day
  • mon: month
• <precision> is the current time rounded to:
  • now: microsecond
  • s: second
  • m: minute
  • h: hour
  • d: day
  • mon: month
