Error 400: One or more TimeSeries could not be written: Points must be written in order. One or more of the points specified had an older start time than the most recent point.

Hi
Appreciate your support as we noticed the below error from prometheus-to-sd pod logs.

```
Error while sending request to Stackdriver googleapi: Error 400: One or more TimeSeries could not be written: Points must be written in order. One or more of the points specified had an older start time than the most recent point.
```
and we can not receive any timeseries points in stackdriver for our custom metrics.

we use django-prometheus to export the custom metrics and we use prometheus-to-sd to scrap and export the metrics to stackdriver.
