I notice in your original post you wanted Epoch Time, but in your blocks you only send a single byte with Clock1.Seconds(Clock1.Now()), which according to its tool tip will be a single number in the range 0-59.
That's way short of an epoch.
The Clock component has extensive formatting options in the FormatDateTime block, which you can use for format a string that hopefully you can send using a UUID devoted to text (outside of my expertise.)
