I wonder if there are any real posters here?  Let's see...

I came across a trivial programming task that must have been solved a
thousand times by other programmers, but it had never crossed my path
until yesterday.  I must be feeling my age because I made a real hash of
tackling it at first.  Anyway, I thought it might be of interest.

Consider any ordered measure that "wraps round" -- bearings in degrees,
minutes in the hour, indeed hours in either the 12 or 24 hour clock.
The problem is to determine if a given value is in the sub-range
specified by a start and an en value.

I was specifically concerned with integer values where the sub-range
includes the start value but excludes the end value.

Though I am not sure this merits the term "puzzle", I suggest that
solutions be posted with some spoiler protection.  Do all the news
readers used by programmers (or ex programmers) all respect the presence
of a form-feed character...

... like this?  Because that's my favourite way, rather than posting
lots of dummy lines before the solution.
