System property when set to TRUE (1) forces a TIME field with value 0 to be converted to a Standard Time of 1. Normally such fields are converted to a Standard Time of 0. You can read this property to get the current conversion rules.

Example:

PROGRAM

ATime TIME
LongTime LONG
CODE
LongTime = ATime
MESSAGE(LongTime) ! will display 0

SYSTEM{PROP:TimeZeroIsLongOne} = TRUE

MESSAGE(LongTime) ! will now display 1

The above code is what appears in the ClarionHelp.chm (as of CW11.1) Below is a fix.

PROGRAM
  MAP  ! required for MESSAGE which appears in builtins.clw
  END 

ATime    TIME
LongTime LONG

 CODE
 LongTime = ATime 
 MESSAGE(LongTime,'#1') ! will display 0

 SYSTEM{PROP:TimeZeroIsLongOne} = TRUE

 MESSAGE(LongTime,'#2') ! will still display 0

 LongTime = ATime
 MESSAGE(LongTime,'#3') ! will now display 1
