Add a clib_time_t * argument to clib_timebase_init(...), to encourage client code to share the vlib_main_t's clib_time_t object. Display the current day / date in GMT via the "show time" debug CLI. Fix the test framework so it processes the new "show time" output format. Type: refactor Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I5e52d57eb164b7cdb6355362d520df6928491711
