What time of day do Domains get released to the zone?

I've heard there's a four hour window during the day when Domains are released... does anyone know that timeframe?

 

I just read this article someone linked too:
How to Snatch an Expiring Domain

"he deletion phase is 5 days long, and on the last day between 11am and 2pm Pacific time, the name will officially drop from the ICANN database and will be available for registration by anybody.

The entire process ends exactly 75 days after the listed expiration date. "

 

noon pacific time.

 

Okay, great... thanks.

 

It happens Sundays too?

 

ye of cuz.
.info is 5am or 3AM EST. i forgot which one. more like 5am.

 

don't most of the registrars auction off expired domains that people had with them?

 

Only GoDaddy does.

 

Is it profitable to auction in godaddy for a Pr2 domain
