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).
For people who are Obsessive Compulsive or those who just wants precise clock, this app is the best for you.
