How to analyse squid logs and wierd time stamps

[keith at smmc.qld.edu.au]

Hi all,
Here is a squid log sample...
1049884671.477    240 10.0.1.121 TCP_HIT/200 744 GET
ftp://ftpav.ca.com/pub/inoculan/scaneng/Siglist.txt - NONE/- text/plain
... Whoa!
Anyone know of a port to analyse this stuff and change what MIGHT be a
timestamp to something a mortal like me can read??
Appreciate help
Keith
