FW-1 and Y2000

After we has tested Firewall-1, we found that Firewall-I was
miscosistent in creating log file.Before Year 2000, Firewall-1 creates the log file in such manner :

xxxMMDDYY.log

where xxx is the time the log file created
MM is the month the log file created
DD is the date the log file created
YY is the year the log file created (1999 will be 99)

Example :
the log file created on Sep 8, 1999 will has the name xxx090899.log
the log file created on Dec 31, 1999 will has the name xxx123199.log

After Year 2000, Firewall-1 creates the log file in such manner :

xxxMMDDYYY.log

where xxx is the time the log file created
MM is the month the log file created
DD is the date the log file created
YYY is the year the log file created (2000 will be 100,
2001 will be 101)

Example :
the log file created on Jan 1, 2000 will has the name xxx0101100.log
the log file created on Feb 28, 2000 will has the name xxx0228100.log

The "100" represents the number of years since 1900. A number of
applications work this way.
