MessageLogging timestamp format

[jerryjonsson]

Hi,

When working with the MessageLogging policy, how do you change the timestamp format to for example YYYY-MM-DD etc..instead of this: "system.timestamp":"1532413540669" ?

So far by reading the documentation I have not found this setting.

This is what I have in my policy:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<MessageLogging async="false" continueOnError="false" enabled="true" name="Message-Logging-1">
    <DisplayName>Message Logging-1</DisplayName>

        <Message>
            {
                "system.timestamp":"{system.timestamp}",
                "environment.name":"{environment.name}",
                "apiproxy.name":"{apiproxy.name}",
