Leave it to Microsoft to come up with something this convoluted:

http://www.microsoft.com/technet/scriptcenter/topics/win2003/lastlogon.m
spx

This seems to work:

require 'date'

last_logon = 128002727440808261

base = Date.new(1601, 1, 1)
base += last_logon / (60 * 10000000 * 1440)

p base.to_s # "2006-08-17"
