Promtail Scrape config - Timestamp issue

Hi there
I am unable to send the original log date to loki, It send only the Scrapped timestamp to loki and when I visualize in Grafana I Could see the logs assigned to current timestamp (ts=****) when the Promtail pushed the logline to loki. Enclosed the details of log, Srape config and Promtail when an o Dry run and inspect mode

Sample Log File

2021-08-11,00:00:01.771,Instruction details goes here,log details goes here.
