Undefined method "utc" with "from" parameter

[bbpennel]

In our hyrax 4 application, which is using blacklight-oai-provider 7.0.2, we are getting periodic errors like the following:

NoMethodError (undefined method `utc' for Sat, 04 Nov 2023:Date):

which appear to occur when clients provide a from parameter specified as a date rather than a date+time, like the following:
/catalog/oai?verb=ListRecords&metadataPrefix=oai_dc&from=2023-11-04

The error only seems to occur if the result would return enough results to trigger resumption token behaviors. I'm not sure where it's happening in the stack, but it would seem that when the from (or until) field doesn't specify time of day, it gets deserialized as a Date, while when it is specified as a full UTC timestamp (with Z as the timezone) it gets deserialized as a DateTime. Only the latter has a utc method.
