Willy Tarreau 64651d1769 BUG/MINOR: opentracing: use 'date' instead of 'now' in debug output
The filter was using "now" in visible output in debug mode, that's
not correct, we should rather use "date" since it's visible. No
backport is needed as it was mostly emphasized by commit 28360dc
("MEDIUM: clock: force internal time to wrap early after boot")
in 2.8..
