Preserving timestamps for prometheus exporter

[nishkrishnan]

I see here that timestamps were explicitly removed from the prometheus exporter. However, shouldn't this be a setting for the user that allows them to choose whether timestamps should be honored or not?

In my case I want to preserve the timestamps that come from the source. How can I achieve that currently?

The time setting is now restored in the latest version and is derived from the metrics data. Exporters should only handle I/O; if you need to modify metrics data, please implement a custom processor.
