This is not about the corner case of a file that was created in the hour of the transition, or even in the week that shifted between non-DST in one year to DST in another (or vice-versa). >From what I understand, we're talking about a file created in DST and checked outside of DST (or vice-versa) in the *same* *year*. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center
