NAME
ACE_System_Time -
Defines the timer services of the OS interface to access the
system time either on the local host or on the central time
server in the network.
SYNOPSIS

class ACE_System_Time
{
public:
enum Sync_Mode { Jump, Adjust };
ACE_System_Time (
const char *poolname = ACE_DEFAULT_BACKING_STORE
);
~ACE_System_Time (void);
int get_local_system_time (ACE_UINT32 &time_out);
int get_master_system_time (ACE_UINT32 &time_out);
int sync_local_system_time (ACE_System_Time::Sync_Mode mode);
private:
typedef ACE_Malloc <ACE_MMAP_Memory_Pool, ACE_Null_Mutex> MALLOC;
typedef ACE_Allocator_Adapter<MALLOC> ALLOCATOR;
ALLOCATOR *shmem_;
long *delta_time_;
};
PUBLIC MEMBERS
ACE_System_Time (const char *poolname = ACE_DEFAULT_BACKING_STORE);

int get_local_system_time (ACE_UINT32 &time_out);
Get the local system time.
int get_master_system_time (ACE_UINT32 &time_out);
Get the system time of the central time server.
int sync_local_system_time (ACE_System_Time::Sync_Mode mode);

specified mode.
