class Runt::REDay

TExpr that matches periods of the day with minute precision. If the start hour is greater than the end hour, than end hour is assumed to be on the following day.

NOTE: By default, this class will match any date expression whose precision is less than or equal to DPrecision::DAY. To override this behavior, pass the optional fifth constructor argument the value: false.
