Yeah, there are frequently ways to figure out what date a relative measure is referring to; it's one of the best things about version control being a true norm in this field. But it's a few extra steps (depending on the UI), and many will not take those steps. They'll just trust it (far beyond when it's relevant), or think "that's probably old" and doubt it (immediately, because old docs are so common). It's relatively minor, but it's extremely easy to prevent, and just a better habit when communicating with the future.
