Error type 247: Software cannot read the time-of-day clock. During this condition, every time stamp in the alarm log entry, error log entry, and software error log entry is potentially inaccurate. In addition, any features that are sensitive to the time of day, such as SMDR, time-of-day routing, ISDN call-by-call will not function correctly.
To resolve the alarm:
Use set time to set the time of day.
Use display time to display the time of day. If the time of day is displayed correctly, wait 15 minutes and verify that the alarm is retired.
