Does anyone have an example of honor_timestamps=true in particular, how to specify the timestamp field?

See https://prometheus.io/docs/instrumenting/exposition_formats/ for
the spec of the exposition format, which also include timestamps.

Instrumentation libraries might or might not support adding
timestamps. Example for the Go library:
https://pkg.go.dev/github.com/prometheus/client_golang/prometheus#NewMetricWithTimestamp

Note, however, that adding timestamps is an extremely niche use
case. Most of the users who think the need it should actually not do
it.

The main usecases within that tiny niche are federation and mirroring
the data from another monitoring system.

In Golang: NewMetricWithTimestamp(t time.Time, m Metric) is the function used to expose metric value along with timestamps.
