Indefinite past

in Uzbek: yaqin o'tgan zamon fe'li

The indefinite past expresses an event or action completed in the past but at a time not specified, or if specified, still outside of the period of time of current relevance to the speaker, even if objectively in the near past.
It is very often a perfect, the results of the event or action being still in effect, and relevant to the present situation.
It may also mark an event or action as already experienced by the agent.

● Indefinite past, with results of the event no longer in effect:

Alisher Navoiy 1441-yili tug'ilgan.
Alisher Navaiy is born in 1441.

Kelgan.
He has come. (and may have gone back as well)

● Indefinite past, with results of the event still in effect:

Men uylanganman.
I am married.

Oliy ma'lumotni qayerda olgansiz?
Where did you get your degree in higher education?

Mana bu paxtadan qilingan.

Ko'p asrlardan beri o'zbeklar va qozoqlar yonma-yon yashaganlar.

● As an experience:

Farg'onada oldin ham bo'lganmisiz?
Have you already been in Ferghana?

● The event might have taken place in the very near (and specific) past:

Bu tezyurar avtobusmi?
Yo'q. U avtobus o'n minut oldin ketgan.

Is it the express bus?
No. That bus has left ten minutes ago.

● The use of bo'l- in its indefinite past form as a predicate for the nominal statives (names, adjectives, bor, yo'q, kerak, mumkin, etc.) indicates that a change of state had or has occured, resulting in a situation relevent either in the past or currently. It might be translated either as 'had become', or 'has become', or 'has been' or 'is':

Men o'quvchi bo'lganman.
I have been a student.

O'rta asrlarda Buxoroda juda katta kutubxona bo'lgan.

● The same state of thing can be either construed as the result of a transformation effective in the past (bo'lgan) or as a state during for a given period of time in the past(imperfective edi). Compare:

Samarqand 1925-1930 yillari O'zbekistonning poytaxti bo'lgan.
