1. Maybe the cloud computers' provider has the appropriate tool?
In this case, if you don't find the tool yourself, you'll have to tell
us which cloud provider are you working with.

2. The 'uptime' command gives the uptime since last reboot.  You may
want to add 'uptime >> /var/log/my_uptimes_log.txt' to the shutdown
script, and rotate & process, using a custom Perl script,
the /var/log/my_uptime_log.txt file each month to total the uptime in
that month.
