Examples with TimeZoneMapping android.timezone.CountryTimeZones.TimeZoneMapping used on opensource projects

Example 1 with TimeZoneMapping

use of android.timezone.CountryTimeZones.TimeZoneMapping in project android_frameworks_opt_telephony by LineageOS.

the class TimeZoneLookupHelper method lookupByCountry.

 * Returns information about the time zones used in a country at a given time.
 *
 * {@code null} can be returned if a problem occurs during lookup, e.g. if the country code is
 * unrecognized, if the country is uninhabited, or if there is a problem with the data.
