==Greyhawke Time==
The Greyhawke year is the same length as the Earth year. That said day length is different. 
*Earth Year: 365 days -- Day 750 minutes
*Greyhawke year: 336 days -- Day 814 (Earth) minutes
The Greyhawke day is 64 Earth minutes longer. They don't typically measure it like that. "Hours" 12 typically from sun up to sun down. "The 5th hour of the day" and so forth. Axial tilt is less so seasons are not as different. Time is usually told via sundials. Mechanical clocks are slowly making a penetration. So if "just a minute:" seems to be taking longer, it is,
Clocks from either place do not work in the other. There is no market for Rollex on Greyhawke unless they make a specially retooled model. Likewise Gnomish pocket watches are not marketable on Earth, except perhaps to collectors.
It has been noted that there is an app for that. The "cross time counter" app will give you a Greyhawke clock on your cell phone. Available in 
Penguin and fOS
