Subject: Does metabolic rate affect perception of time?

A fly perceives us moving at a slower rate than we perceive ourselves. Is this 
determined by it's faster metabolic rate? When people with pacemeakers have 
their heartbeat rate made faster, they can think faster and get better results 
when doing Maths problems. Is this connected? How in general does the speed of 
an organism's metabolism affect it's perception of time? Has this issue been 
researched?
