Narrative:

Descending into anc after six plus hours, all night flight, there was a discrepancy between altimeter settings of ATC/pilot communications. Set 29.83, actual 28.83. 1000' off desired altitude (low). ATC would have brought it to our attention if he called it 'low pressure setting' or 'below 29.92.'
