The scan commit and the review screen looked for an existing reading in the UTC day of the scanned date. A hand-entered morning draw east of UTC sits on the previous UTC day, so scanning the same report wrote the reading a second time. Both checks now compare calendar days: a date-only reading's stated date, or the user's day of a hand-entered instant.
