resolves #1837
bug fix

• Handle 'under a minute' times in Aruba show system
• Fix incorrect time value capturing
  • (ex: if a value was 22 hours, only the last 2 would be captured)

There's a larger uptime parsing issue that I'm working to identify and fix.

Update: Essentially if the time value was greater than a single digit the first digit was being lopped off (probably regex greediness).
