Recently I was installing and configuring a wordpress site after a long time. It was a multilingual website. So I started to use qTranslate

I noticed that the time was showing %I:%M %p . A quick google search landed me on wordpress support website. Then to the qTranslate forum. But the thread was a huge one , and I landed on date and time. And then to internationalization date_i18n. So I changed the function

get_comment_time

to something like the one below.

 date_i18n(get_option('date_format') ,strtotime($comment->comment_date)) 

And it works in a charm :) . I came to know that this only happens when you are using qTranslate. Not explored more on it . So happy hacking !
