Assalamu alaikum
A prayer peformed in congregation, in the masjid, is usually on time. However if the congregation is not performed in the masjid, and elsewhere. You should not delay it.
Allah Most High says:
Woe to the worshippers who are unmindful of their prayer. (107:4-5)
Saad bin Abi Waqqas said: "I asked Allah's Messenger (peace be upon him) about the meaning of 'unmindful,' and he replied: 'It is delaying it (the prayer) up to the end of its prescribed time.'" (Bazar)
And Allah knows best.
