Extract all times from a text field. Note that this includes specific times, times written in prose, and relative times, such as “tomorrow at 3pm”, “one hour from now”, etc.
EXTRACTTIMES("Set a meeting for November 14th at 4pm."): LIST(DATETIME("11/14/2019 16:00:00")) (replace 2019 with whatever the current year is, if you're reading this in the future)
EXTRACTTIMES("Set a meeting for tomorrow at 4pm.") : A DateTime value set to whatever the current date is, plus one day, at 4pm. For example, at time of writing this it is 11/05/19, and so the result would be LIST(DATETIME("11/06/2019 16:00:00"))
