I could imagine a system where any date or time information coming into your eyes or ears would automatically be translated to your preferred time offset. All you would need to do is decide which system of time you wanted and the computer would ensure you always perceived this.

Emails and other text-based methods are simple, analog and digital clocks could be updated on the fly with computer vision techniques and machine learning.
