I recently cross trained into a Thanatos carrier and purchased one from Project Vulcan, and then proceeded to invest in the skill book for a Gallente Dreadnought, the fearsome Moros.
I've got the skills to fly and fit one excepting the Tech II version of the Siege Module. For all the skills to V that I want I have 153 days to go!
Capital Repair Systems V (32 days, 1 hour, 50 minutes, 42 seconds)
Capital Hybrid Turret IV ((none))
Gallente Dreadnought III (1 day, 10 hours, 48 minutes, 8 seconds)
Gallente Dreadnought IV (8 days, 17 hours, 53 minutes, 12 seconds)
Tactical Weapon Reconfiguration V (32 days, 23 hours, 31 minutes, 51 seconds)
Gallente Dreadnought V (49 days, 11 hours, 17 minutes, 46 seconds)
Capital Hybrid Turret V (28 days, 20 hours, 35 minutes, 22 seconds)
Of course, most of that is for the three level V skills at the end so more like 2.5 months to be acceptable levels.
Ah EVE, you heartless monster.
