The information on this page refers to LM-X v4.5.2 and newer, which added the ability to use a remote time server for SYSTEMCLOCKCHECK. If you are using an older version of LM-X, refer to documentation for earlier versions.

The SYSTEMCLOCKCHECK directive specifies the system clock check performed by the client application and license server.

You can set SYSTEMCLOCKCHECK to:

  • Check the clock on the local file system time (the default)
  • Check the clock on a remote Network Time Protocol (NTP) time server
  • Disabled (do not check the clock)

Setting the SYSTEMCLOCKCHECK option is described in FEATURE settings.

Disabling system clock check can improve checkout speed (see Optimizing license checkout speed); however, be aware that disabling system clock check weakens security.

For information about resolving issues users may encounter related to the system clock check, see System clock check.
