When you're searching for a specific email, any type of search parameter that can help you find a message is useful. Digital Inspiration shows off how to really focus your search with an undocumented Gmail search trick that lets you look for emails from a specific time.
A time-based search is useful if you know an email arrived at a specific time, or if you're trying to sort through emails from a very specific block of your day. First, you need to convert your search times over to Epoch time. This converter will do that for you. Then, use the
after parameters in Gmail search like in the screenshot above with your new Epoch time to search through your emails. That's it, the results will be emails that arrived between the two times you specify.
