Time fence messages

To allow the system to log TRACE messages with time fence information, enable bit16 in the ALTPLAN.DEBUGLVL field. The system logs TRACE messages each time inventory or supply is protected by a time fence, such as:

• TIMEFENCE: order xxx
• TIMEFENCE: item yyy
• TIMEFENCE: time fence 021227.080000
• TIMEFENCE: quantity usable 50.0
• TIMEFENCE: quantity protected 20.0
