There is no real-time clock in the TimeProvider 100, so if the TimeProvider 100 is
power-cycled, the time line will be adjusted. The following rules apply and are
intended to keep the time line in the logs from having negative time jumps:
When the TimeProvider 100 powers up, the latest entry in the event and
command logs are checked for date and time. The latest entry is the last one
written into the respective log.
The date and time of the latest entries are compared to see which one contains
the most recent time and date. The most recent date and time will become the
starting point for the internal date and time. In other words, while the unit is
powered, the time line will proceed from that reference.
As entries that will be logged occur, the entries will reflect the current time and
date (based on reference described in the prior bullet). These entries become
candidates for the "latest entry" discovery on the next power-up.
When the CLI command
updated. Since this places an entry in the logs, this provides a new timeline basis
for the next power-up. See
TimeProvider 100 Logs
The TimeProvider 100 provides two types of non-volatile logs: Event and
Command.
Event Log
Event log provides timestamped entries whenever any of the conditions associated
with the events identified in
significant actions such as reboot, resetting time (see
changes to the PLL state also generate log entries. The event log can be viewed
using
show log event
Command Log
Command log provides timestamped entries of user command history. Additionally,
other significant actions such as session log on, session log off, reboot, and
resetting time also generate log entries. The command log can be viewed using
show log command
