Joe Tsai	e42be5a060	tstime/mono: fix Time.Unmarshal (#8480) ... Calling both mono.Now() and time.Now() is slow and leads to unnecessary precision errors. Instead, directly compute mono.Time relative to baseMono and baseWall. This is the opposite calculation as mono.Time.WallTime.

Will Norris	71029cea2d	all: update copyright and license headers ... This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	2 years ago
Emmanuel T Odeke	0daa32943e	all: add (*testing.B).ReportAllocs() to every benchmark ... This ensures that we can properly track and catch allocation slippages that could otherwise have been missed. Fixes #2748	3 years ago
Josh Bleecher Snyder	f013960d87	tstime/mono: make json.Unmarshal of a zero time.Time yield a zero Time ... This was the proximate cause of #2579. #2582 is a deeper fix, but this will remain as a footgun, so may as well fix it too. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago
Josh Bleecher Snyder	142670b8c2	tstime/mono: new package ... Package mono provides a fast monotonic time. Its primary advantage is that it is fast: It is approximately twice as fast as time.Now. This is because time.Now uses two clock calls, one for wall time and one for monotonic time. We ask for the current time 4-6 times per network packet. At ~50ns per call to time.Now, that's enough to show up in CPU profiles. Package mono is a first step towards addressing that. It is designed to be a near drop-in replacement for package time.
