My cat will probably appear around mealtime.
The kanji means present time, but when something "does present time" it is making itself known in the present time. It is showing itself. When it does present time, it causes it to appear or to emerge (as in right now, during the present time).
Since this word consists of a kanji with hiragana attached, you can bet that it will use the kun'yomi reading. You didn't learn that reading with this kanji, so here's a mnemonic to help you: It looks like something is going to appear in front of you. You are so scared and surprised you can't even speak properly: "Are what??" (あらわ) you ask, trying to figure out what's appearing in front of you.
