No source work, performer, or year is documented in the information supplied for this clip, so its origin should not be treated as established. The Portuguese wording is an everyday way of stating the time, and the recording is shared online as a short standalone clip for chats and short videos. It remains in use because the phrase is short, easy to understand for Portuguese speakers, and easy to place where a time is mentioned. That simple, repeatable use, rather than a connection to a known work, explains why it continues to circulate.

A short clip built around the Portuguese phrase for the time just past ten, used as a light reply in chats and videos when someone asks what time it is.
This clip is built around a short Portuguese phrase giving the time as just past ten, with the words hora certa pointing to the correct time and e pouco adding that only a little time has passed since ten. The wording is plain and instantly recognisable to Portuguese speakers, which makes the clip easy to place in a chat or a short video without extra explanation. Its humour comes from the specificity of the statement itself: instead of a general answer, it names one exact moment. Used at the right point in a conversation, it can turn a simple question about the time into a small, shared joke.
