I think you hit an archeology site :-)
The TIM* modules were the first u-blox GPS receiver, introduced
somewhen around 2002/2003 IIRC.
I don't think they are worth much for timing applications these days
(in the time-nut sense ;-), especially considering that the LEA6-T is
available for prices around 50CHF in low quantities.

Considering the age, i'd say that it's +/- 50ns, probably even more.
