> {color:#000000}Our application sends syslog messages to a centralized facility which requires timestamps to be in microsecond format.{color}
> {color:#000000}Our application was so far using log4j 1.12.5’s Syslog appender to send syslog messages, which used to format timestamps with microsecond precision.{color}
> {color:#000000}We are now upgrading to log4j 2.17.0, and don’t see any way to get microseconds included in timestamp for syslog.{color}
> {color:#000000}I am trying to log messages using SyslogAppender with RFC5424 layout.{color}
> {color:#000000}I see that RFC5424Layout.java restricts timestamp to millisecond precision (e.g. 2021-12-22T22:54:33.889-08:00).{color}
> {color:#000000}RFC5424 specification also mentions support for microsecond precision. Here is some text from {color}[https://datatracker.ietf.org/doc/html/rfc5424#section-6.2.3]
> {color:#000000}Example 4{color}
> {color:#000000} 2003-08-24T05:14:15.000003-07:00{color}
> {color:#000000} This represents 24 August 2003 at 05:14:15am, 3 microseconds into the{color}
> {color:#000000} next second. The microsecond resolution is indicated by the{color}
> {color:#000000} additional digits in TIME-SECFRAC. The timestamp indicates that its{color}
> {color:#000000} local time is -7 hours from UTC. This timestamp might be created in{color}
> {color:#000000} the US Pacific time zone during daylight savings time.{color}
>
> {color:#000000}The RFE is to add support for microsecond precision while formatting timestamp in RFC5424 layout{color}
> {color:#000000}A new layout attribute to define millisecond/microsecond precision would be a preferred way.{color}
