  1. 6.2 million metacycles ago, with 1 metacycle = 13 months
  2. "Six Hundred Thousand Meta-Cycles Ago"
  3. Grimlock was trapped in lave for 10,000 years ago, from Simon Furman's blog, Maximus Dinobots #2 Script (W)rap
  4. 700 stellar-cycles ago, so if a stellar cycle is ~7.5 months, then presumptively ~437 years ago.
  5. 29 stellar cycles ago, or 18 years
