So I'm looking at the PBS provider code. It looks like it does not do
any processing on the max wall time. If you say "7" that results in 

#PBS -l maxwalltime=7

in the PBS script. So I should probably conclude that it's Globus that
interprets a plain 7 as minutes and transforms that to 00:07:00.

I suppose the PBS provider could adopt the same scheme.
