TimeMachine data only available before May 2023

[NJAldwin]

Describe the bug

The documentation says that the time machine cannot be used for historic data within the last 5 days, and to use the forecast API instead.

Because "the last five days" isn't exactly defined, I want to make sure I can build in error handling.

If I try to hit the forecast API with a date that's too far in the past, it gives me a 400 Bad Request with the body "Requested time too early, please use https://timemachine.pirateweather.net". Great!

However, if I try to hit the time machine API with a date that's too recent, it gives me a 502 with the body

{
	"message": "Bad Gateway",
	"error": "could not JSON decode Lambda function response: statusCode validation failed"
}

Expected behavior

I would expect hitting the time machine API with a date that's too recent would return a 400 Bad Request, ideally with the latest timestamp that would be available on the time machine, but just a 400 would be fine too.

Actual behavior

Instead, I see an opaque 502 that suggests that an upstream service is returning an error.

Other details

Sample requests (requests made today, 24 December, around noon (1700UTC)

• forecast call that correctly 400s (1 Dec 23:59 ET is before "5 days ago") https://api.pirateweather.net/forecast/REDACTED/42.794697,-71.357407,2023-12-02T04:59:59Z
• time machine call that I believe should 400, but instead 502s (since 22 Dec 23:59 ET is within 5 days) https://timemachine.pirateweather.net/forecast/REDACTED/42.794697,-71.357407,2023-12-23T04:59:59Z
• time machine call that works normally, since it's far enough in the past https://timemachine.pirateweather.net/forecast/REDACTED/42.794697,-71.357407,2023-12-02T04:59:59Z

Also, would it be possible to clarify when exactly the cutoff for "last 5 days" is? Is it based on UTC midnight? Or the location midnight? Or exactly (current date - 5*24h)?
