Is it possible to get Timestamp in output template as DateTimeKind.Utc?

Question

Currently when I use {Timestamp} in an outputTemplate it appears to have been generated by DateTime.Now and therefore being of DateTimeKind.L

Answer 1

It appears the limitation in DateTimeOffset formatting is going to thwart this.

An alternative (so long as the additional property doesn't bloat output somewhere else) is to add a Serilog ILogEventEnricher to the pipeline:

class UtcTimestampEnricher : ILogEventEnricher {
  public void Enrich(LogEvent logEvent, ILogEventPropertyFactory lepf) {
    logEvent.AddPropertyIfAbsent(
      lepf.CreateProperty("UtcTimestamp", logEvent.Timestamp.UtcDateTime));
  }
}

You can then use {UtcTimestamp:o} in your output template to get the value you need.
