Missing info: at what time "today's" image is created?

[EmmanueleVilla]

As per title, when the change in what day is "today" happens?
Looking at the code, it seems that datetime.today().date() returns the local datetime, so what local is that?

I believe this code is run local to Eastern US time, however its been years since I checked this. =brian From: Emmanuele Villa <notifications@github.com> Reply-To: nasa/apod-api <reply@reply.github.com> Date: Tuesday, July 30, 2019 at 4:54 AM To: nasa/apod-api <apod-api@noreply.github.com> Cc: Subscribed <subscribed@noreply.github.com> Subject: [EXTERNAL] [nasa/apod-api] Missing info: at what time "today's" image is created?

To double check this, I set up automated tests for my wrapper to run every 30 minutes over night, starting from minute 15. The tests started failing when my local time passed 00:00 and started working again at 04:00 UTC, so the APOD seems to be published at 00:00 UTC-4 (Eastern Time).

Last failing test (03:46:49 UTC)
First passing test (04:16:38 UTC)

Perhaps the time zone information should be added to the README.

EDIT: Remember DST.
