Custom timestamp in prometheus java client

[Mishanth Pararasasingam (Intern)]

i need to set my custom timestamps to prometheus metrics in java client. But i can't find a way to do that currently. Is there a solution available for this?

there is a similar question in the github. But there seems to be no reply.

https://github.com/prometheus/client_java/issues/767

some places suggest to use a custom collector(https://github.com/prometheus/client_java/pull/494#issuecomment-517914129) but i am not sure how that will solve this and can't find any useful examples.

How ever i have noticed that in go we have that feature (NewMetricWithTimestamp - https://pkg.go.dev/github.com/prometheus/client_golang/prometheus#NewMetricWithTimestamp)  wondering why doesn't java have such.

Has anybody tried doing this with java client. any help is appreciated.
