[mipsel, 6.12.0.199] DateTime.Now fails: System.ArgumentOutOfRangeException: The TimeSpan parameter must be within plus or minus 14.0 hours.

[devizer]

Mono 6.12.0.199 is compiled from source tarball. csc works well. but any call to DateTime.Now fails with exception: System.ArgumentOutOfRangeException: The TimeSpan parameter must be within plus or minus 14.0 hours. The result doesn't depend on TZ env var (PST, UTC, etc)

DateTime.UtcNow works well.

Steps to Reproduce

Mono 6.12.0.199 is compiled from source tarball with default autogen.sh options on the mipsel host without any crosscompilers. libc 2.27, kernel 4.9, gcc 8.4.

Tests using bash:

TMPDIR="${TMPDIR:-/tmp}"
echo 'using System; using System.Diagnostics; class Program { static void Main() { Console.WriteLine($"Hello, World. Version {Environment.Version}. Working Set {Process.GetCurrentProcess().WorkingSet64:n0} bytes"); }  }' > "$TMPDIR/probe-hello.cs"
echo 'using System; using System.Diagnostics; class Program { static void Main() { Console.WriteLine($"UTC NOW: {DateTime.UtcNow}"); }  }' > "$TMPDIR/probe-utcnow.cs"
echo 'using System; using System.Diagnostics; class Program { static void Main() { Console.WriteLine($"NOW: {DateTime.Now}"); }  }' > "$TMPDIR/probe-now.cs"
for f in now hello utcnow; do
  echo ""; echo "PROBE $f"
  csc -nologo -out:"$TMPDIR/probe-$f.exe" "$TMPDIR/probe-$f.cs"
  mono "$TMPDIR/probe-$f.exe"
done

Output:
