Ok guys, little help needed.

When you add the above endings onto the short infinitive of verbs, can you only use them in the past tense?

For example (These might be wrong..):

çalışdikten sonra, televisyonu seyrettim
(AFTER working, I watched the television).

çalışmadan önce, yatağa gittim.
(BEFORE working, I went to bed)


Is it possible to use these types of endings for present tense or future tense phrases? The English equivalent would be "After working I'm going to bed". Or, "After I have flown, I'm going to sleep".

and also this site:

one of the examples there has a few future tense sentences:

-dikten sonra

Ders bittikten sonra öğretmene bir soru soracağım.
(I am going to ask the teacher a question after the class is over.)

Ankara'dan ayrıldıktan sonra sana mektup yazacağım.
(I will write to you after I leave Ankara.)

-meden önce

Tren Londraya varmadan önce öğlen yemeğimizi yİyecektik.
(We shall have had lunch by the time that the train gets to London.)

Babam eve gelmeden önce her şeyi bitireceğim.
(I will finish everything by the time my father comes home.)

so:

"After working I'm going to bed".
çalışdikten sonra yatacağım.

"After I have flown, I'm going to sleep".
uçtukten sonra uyuyacağım.
