FLEXlm Error: cannot connect to license server (15).
Program not run.
FLEXlm Error: Clock difference too large between client and server
The system date, time or time zone is set incorrectly.
The files on your system have a newer creation date than the current time on your system.
The time zone variable (TZ) is set incorrectly on those platforms which support it.
Note: The license manager respects and understands time zones. If the log shows the above error and starting ARC gives the above error, the server and client workstations may not have the same date or time. They must be in sync with Greenwich Mean Time. Up to four hours difference is allowed between the license server and client machines.
Check your system's date, time, or time zone.
Check the files on your system.
Check your TZ variable.
Check the time difference between your client and server.
