The world record for 1-60 in /played-time is 4 days, 20 hours and 52 minutes, and it's important to remember that this run might be including logging off and resting your character in the Inns' around the world (as /played-time only counts when your character is logged in) so it might not be the fastest 1-60 real-time run.
Let's say that you would be able to do max with a /played-time of 5 days and 21 hours (giving you 24 hours and 8 minutes extra). How long would it take you in real-time if you leveled every day?
2 hours a day of gaming: 70 days and 12 hours.
4 hours a day of gaming: 35 days and 6 hours.
8 hours a day of gaming: 17 days and 15 hours.
12 hours a day of gaming: 11 days and 18 hours.
16 hours a day of gaming: 8 days, 19 hours and 30 minutes.
No wonder it took over a month real-time for most players to max out.
