This class implements a real-time timer.
Timing starts at construction or reset().
At construction, you can decide on a number of timer ticks per second; use 1000 to count in milliseconds, 1000000 to count in microseconds, etc. The best resolution achievable is 1us, as this timer relies on the gettimeofday() system call, which has microsecond resolution. Use get() to measure the number of elapsed ticks since last reset(), or getSecs() to get the fractional number of seconds. Use ticksPerSec() to retrieve this value, for example to convert yourself your measured times back to seconds instead of using getSecs().

| Timer::Timer | ( | const int | tickspersec = 1000 |
) | [inline] |
Constructor; immediately start timing.
| tickspersec | number of timer ticks per second; use 1000 to count in milliseconds, 1000000 to count in microseconds, etc. Values larger than 1000000 will throw a fatal error. If 1000000/tickspersec is not integer, a fatal error will also occur. |

| uint64 Timer::get | ( | ) | const [inline] |
Return elapsed time.
Return value is the number of ticks since last reset or since construction.
