Uptime causes commit spam

[helushune]

Uptime is causing commit spam for the -version files.

My environment:
Sweet 1.3 monitoring Cisco 3560 switches (C3560-IPBASEK9-M), Version 12.2(55)SE10

Repo:

1. Install Sweet 1.3
2. Configure sweet to monitor a Cisco switch
3. Wait long enough for Sweet to run an initial collection and a refresh
4. Observe Sweet reports changes for the uptime line under show version. This is displayed both in the git history and console output.
