This prints the last time [lbolt] the thread ran on a cpu .
Example:
> ffffff014b1ec350::walk thread | ::thread -d
ADDR DISPTIME BOUND PR
ffffff014514dc00 4eab -1 0
ffffff014513e160 5293 -1 0
ffffff014513fc60 23ae6 -1 0
ffffff0145237260 4eab -1 0
ffffff01453110a0 16b4a -1 0
ffffff014530e860 23a73 -1 0

ffffff01453213c0 4483 -1 0
ffffff01455617a0 4483 -1 0
Printing the time since it last ran [t - X] would be useful like it
is done for ::cpuinfo wrt to the lbolt.

I am not quite sure what you are proposing. can you please provide an
example.
