FileSystem Created Date not Updating Under Certain Circumstances

[elzik]

With config setup like this:

{
  "WatcherOptions": {
    "WatchedDirectoryPaths": ["C:/Users/<user.name>/Obsidian"]
  },
  "FileSystemOptions": {
    "FilenamePattern": "*.md"
  },
  "FrontMatterOptions": {
    "TimeZoneId": ""
  },
  "Serilog": {
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "MinimumLevel": {
      "Default": "Information",
      "Override": {
        "Polly": "Error"
      }
    },
    "WriteTo": [
      { "Name": "Console" },
      {
        "Name": "File",
        "Args": {
          "path": "C:/ProgramData/Elzik/fmsync/Elzik.FmSync.Worker.log",
          "rollingInterval": "Day",
          "retainedFileCountLimit": "7"
        }
      }
    ]
  }
}

I find that when I set a date to before the year 2000 although I see a message like this:

2025-04-25 10:05:48.290 +01:00 [INF] C:/Users/<user.name>/Obsidian\<file.name>.md file created date updated to match that of its Front Matter.

The created date is blank as the OD sees it. dates after the year 2000 seem to work fine. Strangely, if I then change the logging level to:

 "Serilog": {
    "Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
    "MinimumLevel": {
      "Default": "Debug",
      "Override": {
        "Polly": "Warning"
      }
    }

...the date gets set just fine for dates prior to the year 2000.
