Par2: Stardate (time calculations over 24 hours) 2000-03-08 -- Mark [Originally published by Susan Alchesay in Clarion Tech Journal]
what you are describing is something we call a "StarDate". It is normally
stored in a decimal 13.6 (Makes CPD 21.10 keys happier than reals. Much less
likely to need rebuilding). It is constructed as follows.
StarDate = Today() + (Clock() / 8,640,000)
When formatted as an @d??, you can see the date portion.
For the time, multiply the decimal portion by 8,640,000 to get a clarion
standard time.
In LPM2.5, there are a couple functions for using StarDates. They port over to
CW very easily.
If you don't have LPM, they break down like this:
StarDate( Date, Time )
If Date is omitted, assume TODAY().
If Time is omitted, assume CLOCK().
Return( Today + (Time / 8640000 )
StarTime( StarDate )
If Time is omitted, return( CLOCK(). )
return( ( StarDate - int( StarDate ) ) * 8640000 )
