another clue ; 

Özlemenin saati 

"özleme"  is a verbal noun which can be translated as " longing - missing"

saati ---> time of --> saat + i [ i here is a possesive marking]

so put them together.

" yok[tur] "  is there is not , there is no , it has not 

Ok. then, when we put them together ,we´ll get something like this ;

Özlemenin saati yoktur --->Missing someone [Longing for someone]  has no time.

There is no time of missing someone 

There is no time of longing for someone

ağlamanın olmadığı gibi.

ağlamak --> to cry ,to weep

" ağlama"  again, in verbal noun form  ---> crying 

olmak = to be

ol [be,is] +ma [negative marking] + dık + ı 

olmadığı  ---> that its  not 

gibi --> as, like, just like

ağlamanın olmadığı gibi.

just like crying has not  time

just like crying has no [certain] time

in other words, one can cry any time.. there is no certain time for crying

If you put them all together, we ll have something like this ;

Özlemenin saati yoktur, ağlamanın olmadığı gibi.

There is no  certain time for [of] missing [longing for someone]  just like crying.  [just like there is no certain time for crying]

in other words, one can miss someone anytime just like one can cry anytime..

I hope all these things make sense to you.

may be someone else can give you a better explanation.

good luck with your learning Turkish Archinia.
