no the highest amount of days you can acrue at one time is 255 (its a programming thing), so a guy that is up for all but 21 days his first season, will show 0 years, 255 days of service time roughtly 2/3 of the way thru his second ml season, and remain on that number to the end of the year. At role over for season 3, he'll show 1 year, 83 days of service (255-172=83). He'll play season 3 and beyond in the majors full time (presumably), so that at the end of season 3, he'll show 1 year, 255 days of service (really 259, but there's that 255 programming limit again), and start season 4 as 2 years, 83 days of service time. So the old 20, is still the new 20.
