Timestamp Rounding about serilog-sinks-graylog

[whir1]

I removed rounding and timestamp sends like "1576822447.5433211" but it isn't help you because respose from graylog cluster looks like

"message": { "_id": "190e7480-22ee-11ea-a60d-0242ac120004", "facility": "VolkovTestFacility", "full_message": "null", "gl2_remote_ip": "10.10.76.60", "gl2_remote_port": 62898, "gl2_source_input": "572afd924cedfd0001a14c62", "gl2_source_node": "07040d98-9ce8-4c0e-844b-041cc92994b8", "level": 6, "message": "7", "source": "MOW1-D466", "streams": [ "578f96464cedfd0001689467", "000000000000000000000001" ], "stringLevel": "Information", "timestamp": "2019-12-20T06:01:00.560Z" }

And this timestamp can't sort correctly in Graylog UI

Ок. I build local version without rounding and check it. It send OK, but it still wrong sort in gray log.
Thank you, for help, I close this issue.
It's GrayLog (or GrayLog setup issue)
