Everyone is talking about the time they received their confirmation. I ordered a 38 mm Milanese Loop on launch day (4-6 weeks) and a 38 mm Space Grey Sport on the 26th (3-5 weeks). Neither confirmation email had a time.
The e-mails DO have a date and time that apple sent them. If you're not seeing them, then your e-mail client needs to be reconfigured to display that information.
I am using yahoo.
