Sets the PS5's clock from public NTP servers, for consoles with a flat clock battery

Payload: start an ELF loader on the PS5 first, such as elfldr, which listens on port 9021. Then open this address in a browser on a computer or phone on the same network, with your PS5's address in place of PS5. elfldr downloads the payload and runs it.

About Date and time sync

Meant for consoles with a flat, unplugged or faulty clock battery, where the time is lost whenever the PS5 is powered off completely. With the console online, it gets the time from Cloudflare, pool.ntp.org or Google, sets the clock, shows one notification and exits. Your time zone stays as it was.

It tries Cloudflare's numeric addresses first, so it works even when DNS doesn't. It does need outbound UDP port 123, and a router or provider that blocks that port will stop it. Nothing is installed and no files are changed. Run it once after each boot from a full shutdown.

PS5 Time & Date Sync by Deckerr97

Initial public release.

A standalone, one-shot PS5 payload that restores the console date and time using public NTP servers. It is designed for consoles whose CMOS/RTC battery no longer retains the clock after a complete shutdown.

Features

  • Automatic NTP date and time synchronization
  • Published Cloudflare numeric fallbacks when PS5 DNS is unavailable
  • Cloudflare, pool.ntp.org, and Google Public NTP hostname fallbacks
  • NTP endpoint, version, mode, stratum, request timestamp, and date validation
  • Clock read-back verification after updating
  • Preserves the configured PS5 timezone
  • One notification per payload execution
  • No application installation or file modification
  • Automatically exits after completion

Requirements

  • Compatible PS5 exploit and ELF payload loader
  • Internet access with outbound UDP port 123
  • An execution environment that permits settimeofday

Built using a PS5 Payload SDK package containing firmware definitions through 13.60. Actual runtime compatibility depends on the firmware, exploit, loader, and available permissions.
