Flaky test: "if-modified-since is over 30 ago"

[Ben Vinegar]

I noticed this test started failing at 11:00 PM EST. It does mess with dates/timezones, etc so likely a situation where the day boundaries aren't accounting for timezones.

This could be a problem with the test (because it populates test data with dates/timestamps), or it could be that we're not respecting timezones properly in our if-modified-since server handler.
