Message:

Date/Time: Ensure that get_feed_build_date() correctly handles a modified post object with invalid date.

• Clarify in the documentation that the function returns false on failure.
• Consistently pass the return value through the get_feed_build_date filter.

Props Rarst, dd32, azaozz, tellyworth.
Fixes #48957.
