Time Zone Data

The Time Zone Data module updates daylight saving time (DST) and time zones on
Android devices, standardizing both the data (which can change frequently in
response to religious, political, and geopolitical reasons) and the update
mechanism across the ecosystem. For more details on Time Zone Data, see
Time Zone Rules.
Changes in Android
Android 10 deprecates the
APK-based time zone data update
mechanism (used in Android 8.1 and Android
9) and replaces it with an
APEX-based module update mechanism. AOSP
continues to include the platform code necessary for APK-based updates, so
devices upgrading to Android 10 can still receive
partner-provided time zone data updates through APK. However, the APK update
mechanism shouldn't be used on a production device that is also receiving
module updates, as an APK-based update supersedes an APEX-based update (that
is, a device that receives an APK update ignores APEX-based updates).
The Time Zone Data module is in
APEX format and
is available for devices running Android 10 or higher.
