Maybe a Date_Calc one, allowing arithmetic operations on 5-byte time
values.
ADD and SUB would be obvious. Maybe an option to return the result as
centiseconds, or minutes, or hours, days, weeks, months, years for
example. The centiseconds one would need to return in a 5-byte buffer. The
others could, for example, return as the "convert to ordinals" one.
Would reverse calculations be useful, returning a 5-byte date-time?
I'm not sure it would need to handle dates as strings - the Territory
module is the route for that.
