Q: so my ipod just told me i need to change my lock code in the next 60 minutes, why????

Seems like a scam since Apple does not give you such warning that I know about. Were you on a website when this happened?

Sites can use JavaScript to popup messages like that.

What apps/notification do yo allow on your lock screen? Seems like one of those is giving you that bogus message.

Take a look at http://apple.stackexchange.com/questions/124771/is-the-message-you-must-change-y our-passcode-within-60-minutes-valid-non-mal

It may be that you've chosen a weak password and are being required to update it or this is a company device and there is policy to enforce password changes now and then. As long as you make a change using the settings widget on the device you're not supplying credentials to some third party so it should be safe to do so.
