The first screenshot of the alleged Rekieta tweet was posted at 5:01 AM UTC.
The second screenshot was posted at 4:59 AM UTC and has a "edited at" time for Rekieta's tweet of 12:51 AM (likely EDT, as this would mean Rekieta last edited it at 4:51 AM UTC, or 11:51 PM local time).
The user who posted the first screenshot also
posted a reply to a Rekieta tweet at 4:54 AM UTC. However, the tweet from Rekieta he was responding to has been deleted. There is also a similar
reply to a deleted Rekieta tweet with a time of 4:51 AM UTC which likely corresponds to the 1 reply visible in the first screenshot.
This satisfies me that the screenshots are legitimate.
