please help!

Is RTP in chemistry (thermochemistry and electrochemistry) referring to room temperature of 25degreeC (or 298K) and 1atm, or 20degreeC (293K) and 1atm?

In my lecture notes on gas law, they stated RTP refers to 25degreeC, but in my electrochem lecture notes they mentioned specifically that rtp is 20degreeC.

What???

Please please please help! Thanks! I tried googling but i got even more confused.
