  This is an absolute must in radio software. The workaround I've seen in other software is having a set of recordings corresponding to hours and minutes, besides some optional start and end tracks for every reproduction of the clock.
  
  So you would have:
  - An hours folder with 00.mp3, 01.mp3, 02.mp3 ... 23.mp3
  - A minutes folder with 00.mp3, 01.mp3, 03.mp3 ... 58.mp3, 59.mp3
  - A start.mp3 track that would say something like "In our radio the current time is..."
  - An end.mp3 track that would say ".... now keep enjoying our music."
  
  Then the software can set up any radio clock for any time it needs using those files, ex: For 2:03 p.m. would reproduce start.mp3 + hours/14.mp3 + minutes/03.mp3 + end.mp3.
  
  In some scenarios I've seen software pre-rendering the current time every minute, so is ready to play at any time, by mixing the start, hour, minute, and end track into one (current-time.mp3).
  
  This method is commonly used, so you can find these sets of hours/mins tracks online pre-recorded

  I use a cron job on the host that runs every minute and produces a "/tmp/saytime.wav" using a TTS engine. The file can easily be mounted into the docker and you can always simply play it while being sure that it will announce the correct time (and message).

  See "Time & Station ID Announcement (TOTH) in AzuraCast using Text-To-Speech" (https://blog.syvi.net/tech-snippets/time-und-station-id-announcement-toth-in-azuracast-using-text-to-speech) for a solution using TTS and just ONE FILE to be used in a playlist—anytime.

  @Moonbase59 the snippet link you posted is no longer valid.

  If you are still looking for a way to (at least) create the audio for a time call, you could do something similar to what I've done for a "live" news read here: https://github.com/troykelly/live-news-break
  
  It runs in a container, and generates an hourly (or other) news read to be played out via the playout software.

  It would need to take into account the delay before a listener hears it too..

  Hello, while this functionality is being implemented, we have solved the issue with the hourly signals by adding this to the Liquidsoap configuration after:
  
  # Handle "Jingle Mode" tracks by replaying the previous metadata.
  radio = azuracast.handle_jingle_mode(radio)
  
  
  señal_horaria = single("/var/azuracast/stations/granja/media/senales_horarias/pitos.mp3")
  horarias = switch(id="time_signal_switch", [
  (predicate.once({ 0m }), señal_horaria)
  ])
  # smooth_add mezcla suavemente sin cortar
  radio = smooth_add(
  duration=0.2, # Duración de la transición (0.2 segundos)
  p=0.4, # Música baja al 40%
  normal=radio, # Fuente principal
  special=horarias # Señales horarias
  )
  
  I hope it’s useful to you.
