Member Typedef Documentation

Member Enumeration Documentation

Enumeration types to specify mode of synchronization with master clock. Jump will set local system time directly (thus possibly producing time gaps or ambiguous local system times. Adjust will smoothly slow down or speed up the local system clock to reach the system time of the master clock.

Member Function Documentation

int ACE_System_Time::get_local_system_time ( time_t &  time_out)
static

Get the local system time, i.e., the value returned by ACE_OS::time().

int ACE_System_Time::get_local_system_time ( ACE_Time_Value time_out)
static

Get the local system time, i.e., the value returned by ACE_OS::time().

int ACE_System_Time::get_master_system_time ( time_t &  time_out)

Get the system time of the central time server.

int ACE_System_Time::get_master_system_time ( ACE_Time_Value time_out)

Get the system time of the central time server.

int ACE_System_Time::sync_local_system_time ( ACE_System_Time::Sync_Mode  mode)

Synchronize local system time with the central time server using specified mode.
