Use Local Time for StackTrace timestamp in ServiceStack

Question

In the stacktrace property of the ResponseStatus object in a servicestack response, there is a time stamp as follows:

"StackTrace": [GetEmployee: 8/12/2015 9:09:35 PM]

The timestamp, however, is in UTC time. Is it possible for me to configure servicestack to always return the server (or local) time instead of UTC for stacktrace errors?

ServiceStack consistency uses DateTime.UtcNow for performance and uniformity throughout the code-base. You can't change the hard-coded usage of DateTime.UtcNow directly but you can override the OnExceptionTypeFilter in your AppHost to modify/decorate the returned ResponseStatus which will let you replace the existing DateTime to DateTime.Now with something like:

public override void OnExceptionTypeFilter(
    Exception ex, ResponseStatus responseStatus)
{
    base.OnExceptionTypeFilter(ex, responseStatus);

    var parts = (responseStatus.StackTrace ?? "").SplitOnFirst(']');
    if (parts.Length != 2) return;

    var requestName = parts[0].Substring(1).SplitOnFirst(':')[0];
    responseStatus.StackTrace = "[{0}: {1}]{2}".Fmt(
        requestName, DateTime.Now, parts[1]);
}
