Server and Client disagree on upload-time format

[nickburlett]

When running hackage-mirror, the client code attempts to set the date in ISO 8601 format (%Y-%m-%dT%H:%M:%SZ), but the server expects a locale-based string (%c) as input. This leads to incorrectly mirrored upload-times on the server, and Could not parse upload time errors from the client.

Server code:

hackage-server/Distribution/Server/Features/Mirror.hs

Line 227 in eadf543

Client code:
