Can I buy 1 month of WoW time?

Excuse me, I'm a bit confused about the options for purchasing game time for World of Warcraft. I'm specifically wondering if it's possible to buy just one month of game time, without committing to a longer subscription period. Could you please clarify if this is an option and, if so, how I can go about doing it? I'd really appreciate any guidance you can offer on this matter.
