[Solved] Msg 242, Level 16, State 3, Line 2 The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

I have these values 

100 900 1300

in int format , now i want to convert them to hh:mm:ss tt format in sql. How can this be done ? I have used this query

declare @nvsDateTime int;set @nvsDateTime = 100;
select convert(datetime, convert(varchar(10),CURRENT_TIMESTAMP,120)  + ' ' + stuff(ltrim(@nvsDateTime),3,0,':') ) AS Answer

But it is only converting 100 and 1300 but not 900 and giving me this error :

Msg 242, Level 16, State 3, Line 2 The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.
