188.8.131.52. The HEADER message part
The HEADER part contains a timestamp and the hostname (without the domain name) or the IP address of the device. The timestamp field is the local time in the Mmm dd hh:mm:ss format, where:
Mmm is the English abbreviation of the month: Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec.
dd is the day of the month on two digits. If the day of the month is less than 10, the first digit is replaced with a space. (For example Aug 7.)
hh:mm:ss is the local time. The hour (hh) is represented in a 24-hour format. Valid entries are between 00 and 23, inclusive. The minute (mm) and second (ss) entries are between 00 and 59 inclusive.
The syslog-ng application supports other timestamp formats as well, like ISO, or the PIX extended format. For details, see the
