Reportedly (wordltimezone.com, some Spanish media) Honduras chose to follow Guatemala and will observe DST [this weekend]

Thanks for the heads up. I can't find any more-official confirmation, but if it's good enough for the AP and NACION, it's good enough for me, particularly since the change takes effect this weekend.

My theory is: DST ends Saturday 02 September 2006 24:00 local time.

That's a reasonable guess (it's 2 hours away from our guess for Nicaragua). Another possibility is the last Sunday in September at 00:00, which is what they did the last time they observed DST. I think I'll assume that for now. Here's a proposed patch to the tz database for this.
