Jim, thanks for that quick tip. It has some slight drawbacks though. I get
all January 1sts.

eg.

proxy:~ # ruby -pe '$_.gsub!(/^(\d+)/, Time.local "\\1".to_i).to_s)'
/var/log/squid/access.log

// ruby -pe '$_.gsub!(/^(\d+)/, Time.at($1.to_i).to_s)'

Thanks Jason. i removed the $_ to make it neater. But it has some drawbacks
still. Seems that the date/time gets fixed at January for the first record
and then fixed at the start date thereafter..... In other words, the
date/time doesn't change...

eg.
proxy:~ # ruby -pe 'gsub!(/^(\d+)/, Time.at($1.to_i).to_s)'
/var/log/squid/access.log

James, you thought it right. Thanks. It's the shortest so far and no $_ and
$1 there! And the block form gives me emphasis on what to concentrate on.
Cool -and it simply works!

Thanks for the great tip.

Oops. I should have submitted the block version of gsub.
