sandbox: Add test function to advance time
Add a function that maintains an offset to include in the system timer values returned from the lib/time.c APIs. This will allow timeouts to be skipped instantly in tests Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Acked-by: Simon Glass <sjg@chromium.org>
