TimeOfDay.roll

TimeOfDay roll(string units)(long value) if (units == "hours") ref @safe pure nothrow @nogc

Adds the given number of units to this TimeOfDay, mutating it. A negative number will subtract.

The difference between rolling and adding is that rolling does not affect larger units. For instance, rolling a TimeOfDay one hours's worth of minutes gets the exact same

TimeOfDay.

Accepted units are "hours", "minutes", and "seconds".

Parameters

`units`	The units to add.
`value`	The number of `units` to add to this TimeOfDay.

Returns

A reference to the TimeOfDay (this).

TimeOfDay roll(string units)(long value) if (units == "minutes" || units == "seconds") ref @safe pure nothrow @nogc
