No. That's only half of the story.

Which seems logical to me, as "date" is the command to read  and  set
the RTC.

I disagree. Just RTFM...

Quoting the README:

- Timestamp Support:
                When CONFIG_TIMESTAMP is selected, the timestamp
                (date and time) of an image is printed by image
                commands like bootm or iminfo. This option is
                automatically enabled when you select CFG_CMD_DATE .
