Stuck on final puzzle from treasure hunt — numbers, dots, cubes, slash

Hey everyone,

I’m taking part in a treasure hunt with 16 puzzles divided into 4 groups:

• 4 photo locations to find
• 4 text riddles to solve
• 4 coordinates to decipher
• 4 coded texts to decode

After solving all 16 we received extra clues in PDF form — a sequence of numbers and cubes, plus symbols for “dot above”, “dot below”, and a slash, exactly in the order shown in the image.

Important clarification: the clues shown in the image refer to the number of the puzzle we solved. For example, a cube indicates puzzle #1, meaning it comes from the first group of four puzzles. Each cube corresponds to the index of the puzzle it came from (so “cube” = puzzle 1, another cube = puzzle 2, etc., mapped to the 1–16 ordering).

We have a theory: by plotting the coordinates of the four locations where we found the same-index clue (for example, the four places where we found clue #1 — one from each group) and then finding the midpoint/centroid of those four points, each set led us to a spot where we found what looks like a fifth poneglyph. At one of those spots we scanned a QR code that said: “find the right moment to capture emotions”.

We think the photo we attached (below) might encode a date and time — i.e., we may need to scan or photograph the QR code at that specific date/time shown in the photo. But we can’t figure out how the remaining part of the code (the numbers, the dot-above / dot-below markers, and the slash) maps to a usable date/time or action.

Our problem: we don’t know how to convert the sequence of numbers + dots + slash into whatever final step is required (date/time, coordinates, or something else).

Any ideas from puzzle solvers or One Piece fans? Any decoding approaches we should try, or examples of similar puzzles where dots mean “AM/PM”, or slashes separate date components, etc.? Thanks in advance — we’ll post the photo and the PDF snippet below.
