Log timestamp and loki timestamp always different

Grafana Loki
,

when i use the curl command put a log to loki, like this

curl -X POST "https://example:port/loki/api/v1/push" \
-H "Content-Type: application/json" \
-d '{
  "streams": [
    {
      "stream": {
        "account": "demo",
        "environment": "test",
        "type": "application"
      },
      "values": [
        ["1735328400000000000", "{\"log_message\": \"simple log message\", \"actual_time\": \"2024-12-27T17:00:00+00:00\"}"]
      ]
    }
  ]
}'

and check the log in grafana，

log and loki timestamp are different.
loki timestamp is run curl command’s time.

my loki config reject_old_samples and reject_old_samples_max_age are default.
how to fix the timestamp problem?

Try testing with a timestamp that’s not in the future (for example 1735308782000000000, which is when i wrote this reply). You’ll need to change your labels too to avoid conflict test (say account: demo1).

      ]
    }
  ]
}'

In my Grafana console hava same problem.

loki timestamp still at run curl command’s time, not the log time (2024-12-27T02:53:02+00:00).

What other ways can I test to resolve this issue?
