Defined in:

Overview

Describes a field as a Time field. Currently this means that it has both a time and a date.

Options

  • :before [time] - specifies that the value must predate the given time (as object or string)

  • :after [time] - specifies that the value must postdate the given time (as object or string)

  • :distance [range] - specifies a range of seconds that provide an minimum and maximum time value to be calculated from the current time.
