"Updated on" fidelity

Description of development task:

Based upon this article I'd like us to select an industry best practice format for timekeeping: https://www.moesif.com/blog/technical/timestamp/manage-datetime-timestamp-timezones-in-api/

Options:

1. If you want human readable use ISO 8601 (yyyy-MM-dd'T'HH:mm:ssZ)
2. Otherwise use Unix Epoch Time

Why? Well didn't think of that originally as important... but now that it's created I don't want it to be limited if we find interesting ways/date related to it such as, "What time of day do most updates to KSATs happen?"

Acceptance Criteria:

• AC 1 - Pick a format
• AC 2 - Update scripts to implement
