Is it true it can take up to 2 hours for a paypal transaction?

someone sent me money but it hasnt gone thru. they said it can take 2 hours. are they lying? did they really send the cash?

I have worked with Paypal a lot, and I have never had it take as long as 2 hours. It normally works instantly for me.
But they may not be lying. I think that it might take longer depnding on the speed of the person's server.

well just 2 let every1 know. they were lying
