Date time format in access.log

[Dayo Adewunmi <contactdayo@xxxxxxxxx>]

Hi all

In /var/log/squid/access.log on Ubuntu 8.04, squid 2.6.18-1ubuntu3 the 
log lines get
written to file with the epoch time, instead of the human-readable time.
How can I get squid to write to access.log with human-readable time?
Thanks

Best regards

Dayo
