Use this routine to set the wall clock time functions.
Important: The Series B, BASIC module does not update the wall clock
for Daylight Savings Time. You must do this manually. (The Series A,
BASIC module, revisions A, B, C and D update the fall time change
correctly but update the spring time change on the third weekend of April
instead of the first weekend.)
Input and Output Arguments

arguments are the wall clock time functions:
H = hours (0 to 23)
