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.
