ClockSync synchronizes device system clock with atomic time from Internet via NTP (Network Time Protocol).
Useful if provider doesn’t support NITZ, sends incorrect time or if your device/ROM has heavy clock drift.
There are 2 modes: automatic for root users and assisted manual mode for users without root (rootless mode).
Rootless mode features:
– automatic atomic time retrieval with configurable interval
– notification when offset exceeds user set threshold
– assisted manual synchronization with the hint what time/date to set
– precision between 1 and 30 seconds (because Android doesn’t allow to set seconds)
– 1 second precision if your device resets seconds on Set (most Samsung and some HTC devices)
– Greenwich Time Signal assisted sync if device resets seconds
Root mode features:
– automatic sync with configurable interval
– accuracy is ~1-20ms depending on your connection and NTP server
– statistics (average drift per day, total time corrected)
– customizable NTP/SNTP server and timeout
– displays current date or time since last sync
– NTP server details dialog
– 3 color schemes (dark, light, default)
– 12-hour or 24-hour clock format
– time zone detection and adjustment based on geo location
– system time zone override with custom offset
– time zone management based on latest Olson tz database (zoneinfo)
– optional haptic feedback and sync notification
– clean and easy to use interface (tap screen values or use menu)
Root is required because of Android security restrictions (user apps cannot set time).
