[hobbit] Alert if a list of devices that are not related are all down?

Tue Oct 6 22:38:44 CEST 2009

If you need to convert 'seconds since Jan 1, 1970' format to another format, and have GNU date command available, you can use '@seconds' with the '-d' flag:

Using SuSE Linux 10.1:
# date -d "jan 23 2008 14:32:05" +%s
1201116725

# date -d "@1201116725"             
Wed Jan 23 14:32:05 EST 2008

Using MacOS X:
date -r 1201116725
Wed Jan 23 14:32:05 EST 2008
