Hi! I used the "survey_date" tag because I wanted to be more specific and indicate that I did indeed survey in person these opening hours at that date.

However, it's clear that "check_date" is the de-facto standard in OSM for indicating when something was last verified as up-to-date, and the detail that the source of the check date is a survey is also already indicated in my changeset tags.

So, thank you for making this correction! I have converted the rest of my "survey_date" tags to "check_date" (see Changeset: 149030812) and verified this changeset and your other earlier one (Changeset: 149012913) as good on OSMCha because I agree that this is a good change. Much appreciated!
