From 197180031bad1e51ee032d30d8a095a51207454c Mon Sep 17 00:00:00 2001 From: Dave Barach Date: Wed, 11 Mar 2020 10:31:36 -0400 Subject: vppinfra: refactor clib_timebase_t 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.
