Certainly sounds like Julian-day-hour-minute-second to
me, just like all the
timecode displays I've ever seen going back a good chunk of a century :-). I
looked through the truetime schematics I have and none of yours match
exactly so maybe some other brand.
I googled for photos of truetime devices and did not recognize the
style and spacing of the LEDs. Also, as I said, LCDs are much more
common now than LEDs. I have approximate dates for these displays
(the newer ones are from the early-to-mid-1990s), so it's been hard to
restrict the search to that era without a hint as to a vendor.
Some similar displays are sometimes used in video and
movie editing and
production (think those LED slates), although there the 3- or 4-digits
would probably not be day, but some sort of sequence number, dunno for sure,
I only briefly touched Hollywood :-)
ISTR those use MM-DD-YY or YYYY HH:MM:SS.fff or something similar.
Many more digits than I have.
