Can someone help regarding timestamp in prometheus

[PK]

Hi everyone,

I am using C++ client library for Prometheus.

In Golnag: For Adding timestamp along with the value, we have an API  NewMetricWithTimestamp(time, metric). 

I am searching the same for C++.
Can anyone help, how we can add timestamp along with the value using C++ client library?

For eg: my_metric(label name, label value) 123 1636534467

where 123 is the metric value and 1636534467 is a timestamp in epoch format.
