<![CDATA[appliance clock running slow]]>My 5100 time runs slow and keep falling behind, although it updates OK when it checks NTP server.

If there a backup battery which I need to replace?

Seems to be losing 1-2 sec per hour.

A slow (or fast) clock is because the clocks in PCs are cheaply made, sometimes they do not keep good time. It is not uncommon for a PC clock to be off by seconds each day.
If it is an issue decrease the time between time checks.
