The Time class holds a time moment with microsecond accuracy
inline Time ()
| Time |
Constructs a Time object from the current time
inline Time (u_int64_t usec)
| Time |
Constructs a Time object from a given time
Parameters:
usec | Time in microseconds |
inline explicit Time (const struct timeval* tv)
| Time |
Constructs a Time object from a timeval structure pointer
Parameters:
tv | Pointer to the timeval structure |
inline explicit Time (const struct timeval& tv)
| Time |
Constructs a Time object from a timeval structure
Parameters:
tv | Reference of the timeval structure |
inline ~Time ()
| ~Time |
Do-nothing destructor that keeps the compiler from complaining about inlining derivates or members of Time type
inline u_int32_t sec ()
| sec |
[const]
Get time in seconds
Returns: Time in seconds since the Epoch
inline u_int64_t msec ()
| msec |
[const]
Get time in milliseconds
Returns: Time in milliseconds since the Epoch
inline u_int64_t usec ()
| usec |
[const]
Get time in microseconds
Returns: Time in microseconds since the Epoch
inline operator u_int64_t ()
| u_int64_t |
[const]
Conversion to microseconds operator
inline Time& operator= (u_int64_t usec)
| operator= |
Assignment operator.
inline Time& operator+= (int64_t delta)
| operator+= |
Offsetting operator.
inline Time& operator-= (int64_t delta)
| operator-= |
Offsetting operator.
inline void toTimeval (struct timeval* tv)
| toTimeval |
[const]
Fill in a timeval struct from a value in microseconds
Parameters:
tv | Pointer to the timeval structure |
void toTimeval (struct timeval* tv, u_int64_t usec)
| toTimeval |
[static]
Fill in a timeval struct from a value in microseconds
Parameters:
tv | Pointer to the timeval structure |
usec | Time to convert to timeval |
u_int64_t fromTimeval (const struct timeval* tv)
| fromTimeval |
[static]
Convert time in a timeval struct to microseconds
Parameters:
tv | Pointer to the timeval structure |
Returns: Corresponding time in microseconds or zero if tv is NULL
inline u_int64_t fromTimeval (const struct timeval& tv)
| fromTimeval |
[static]
Convert time in a timeval struct to microseconds
Parameters:
tv | Reference of the timeval structure |
Returns: Corresponding time in microseconds
u_int64_t now ()
| now |
[static]
Get the current system time in microseconds
Returns: Time in microseconds since the Epoch
u_int64_t msecNow ()
| msecNow |
[static]
Get the current system time in milliseconds
Returns: Time in milliseconds since the Epoch
u_int32_t secNow ()
| secNow |
[static]
Get the current system time in seconds
Returns: Time in seconds since the Epoch
unsigned int toEpoch (int year, unsigned int month, unsigned int day,
unsigned int hour, unsigned int minute, unsigned int sec, int offset = 0)
| toEpoch |
[static]
Build EPOCH time from date/time components
Parameters:
year | The year component of the date. Must be greater then 1969 |
month | The month component of the date (1 to 12) |
day | The day component of the date (1 to 31) |
hour | The hour component of the time (0 to 23). The hour can be 24 if minute and sec are 0 |
minute | The minute component of the time (0 to 59) |
sec | The seconds component of the time (0 to 59) |
offset | Optional number of seconds to be added/substracted to/from result. It can't exceed the number of seconds in a day |
Returns: EPOCH time in seconds, -1 on failure
bool toDateTime (unsigned int epochTimeSec, int& year, unsigned int& month,
unsigned int& day, unsigned int& hour, unsigned int& minute, unsigned int& sec)
| toDateTime |
[static]
Split a given EPOCH time into its date/time components
Parameters:
epochTimeSec | EPOCH time in seconds |
year | The year component of the date |
month | The month component of the date (1 to 12) |
day | The day component of the date (1 to 31) |
hour | The hour component of the time (0 to 23) |
minute | The minute component of the time (0 to 59) |
sec | The seconds component of the time (0 to 59) |
Returns: True on succes, false if conversion failed
inline bool isLeap (unsigned int year)
| isLeap |
[static]
Check if an year is a leap one
Parameters:
year | The year to check |
Returns: True if the given year is a leap one
