A day has 24 hours; you want to assign a certain value to each hour, a linear relationship that could be calculated has been rejected; so I put the desired values as defined by YOU into a 24 element array and have it indexed by the hour (using awk features) for output.
Look e.g. what you requested for 3pm (15h) and see what B[15] is.

This module provides routines to format dates. They correspond to the libc routines. &strftime() supports a pretty good set of coversions -- more than most C libraries. strftime supports a pretty good set of conversions. The POSIX module has very similar functionality. You should consider using it instead if you do not have allergic reactions to system libraries. GENESIS
