localHub=TRUE does not keep appropriate snapshot date

localHub=TRUE does not keep appropriate snapshot date... See example with "older version of R"

> eh = ExperimentHub()
snapshotDate(): 2025-10-07

> eh = ExperimentHub(localHub=TRUE)
Using 'localHub=TRUE'
  If offline, please also see BiocManager vignette section on offline use

Because we get the version/date by querying bioconductor.org configuration mapping biocversion/R/date .... how can we get around this? cache the config with the hubs to reference??
