How do I write a layout for NLog that outputs time with milliseconds like this 11:32:08:123?
I use ${date:format=yyyy-MM-dd HH\:mm\:ss} but I need more time precision in my logs.

${date:format=yyyy-MM-dd HH\:mm\:ss.fff}
According to the NLog documentation, you can use C# DateTime format string.
This is a pretty good reference for DateTime format strings: http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm

${longdate}
Another alternative to the format suggested by harriyott is to use the ${longdate} renderer. It should automatically give you the precision you need.

Another alternative solution is to use the ISO 8601 format '1998-02-23T14:23:05.555'. This format is independet of the languange of the sql server.
${date:format=yyyy-MM-ddTHH\:mm\:ss.fff}
