> WARNING: Using TrueCrypt is not secure as it may contain unfixed security issues
The fact that they use awkward wording that contains words whose first letters that start with NSA (not secure as) is pretty suggestive that you are right.
What would you suggest instead? It's a good way to convey unfounded paranoia or to acknowledge that what you're saying sounds like a conspiracy theory.
No the actual message is "Using TrueCrypt" -> UTC -> Coordinated Universal Time. The real culprit are the time thieves as explained in the book "Momo and the Time Thieves".
