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.
ACE_System_Time::ACE_System_Time | ( | const ACE_TCHAR * | poolname = 0 | ) |
Default constructor.
ACE_System_Time::~ACE_System_Time | ( | void | ) |
Default destructor.

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.
