Timestamped files on SD card
dctucker
San Diego, CA, USAPosts: 5
As I was backing up my SD card, I was reminded that files saved by the Deluge are all given a default timestamp value. This is because the Deluge does not have the necessary hardware to keep track of real-world time while powered off, and currently no time synchronization capabilities.
I'm opening this discussion to try and scope out what it would take to reliably store files with a non-default timestamp.
Draft proposal:
- Track the time elapsed since powered-on ("uptime") using existing timers
- Allow a specific SysEx message to be received that sets a value on the Deluge representing current known world time
- When a file is stored, timestamp with estimated world time = uptime + last known world time
- Periodically store current estimated world time to SD card (every minute ought to be a reasonable period)
- Load known world time from SD at power-on.
