|Type:||yes or no|
Description: Specifies whether syslog-ng should accept the timestamp received from the sending application or client. If disabled, the time of reception will be used instead. This option can be specified globally, and per-source as well. The local setting of the source overrides the global option if available.
To use the S_ macros, the keep-timestamp() option must be enabled (this is the default behavior of syslog-ng OSE).
