android Alarm Manager Service Kernel time zone update to

has anyone noticed that when time passes from 23:59 to 00:00 which is a new day, emulator shows a message like:

08-06 00:00:00.092: DEBUG/AlarmManagerService(52): Kernel timezone updated to -180 minutes west of GMT

may it mean that there is a broadcast in the system fired at just after the day chaged? And i wonder开发者_运维百科, can it be possible to put a broadcastreceiver called with this notification so i can manage my activity or some other components of my application freely knowing that date has just changed?
