is the ability for seeds to germinate governed by a `time clock` or by
temperature?

There are lots of mechanisms depending on which seed you are talking
about - eg some will germinate only in the light and not when buried.

I am thinking of taking some nasturtium seeds to turkey (from
UK) to plant at xmas where the weather will be low 60s in the hope they will
germinate and flower for me going back in May. Does this sound feasable?

Eminently feasible. Nasturtiums are basically perennial, but we grow
them as annuals because they are very frost sensitive. Once grown, the
seem to carry on flowering forever -certainly ones in my greenhouse
carry on flowering all winter.

But I don't know how they'd feel about the heat of the Turkish summer.
