You say this, but then you discover $HISTTIMEFORMAT
which helps records when you last ran a command as a comment in the history file and Ctrl+R won’t tell you that information.
The hard part with adopting that, though, is editing in plausible looking dates for commands that were issued before it was set up (or choosing not to and dealing with the confusion until those commands disappear off the top of the history).
There are dozens of us. Dozens!
