Narrative:

Climbing out of abq on an absolutely beautiful day with very little traffic, pretty quiet on the radio, smooth air, enjoying the flying. Did not reset altimeter from 30.22 to 29.92 passing through FL180. After 'level' at FL290 for quite awhile, the center controller said, 'I've had you 300 ft low for quite a while, check your altimeter.' what happened: I've been on this airplane for over 2 1/2 yrs and I've gotten complacent. Must remain vigilant on even the easy days.
