We already have $TEST_DATE_NOW, which "test-tool date" will respect for various commands to pretend that it's currently a particular time. I think you'd need to add a sub-command similar to "relative" (which directly calls show_date_relative()) which calls into the "human" code. Note that there _isn't_ a way to have actual non-test git programs read the current time from an environment variable (as opposed to actually calling gettimeofday()). -Peff
