How Can I Change Time Zone and/or Time Format

["Vadim Pushkin" <wiskbroom@xxxxxxxxxxx>]

Hello;

I find it difficult to correlate data from my access.log, which starts off 
with something like this:

1175633093.114

How can I change "log_access?" into something in EST or a time format that 
others, myself included, can read?

Thank you,

.vp
