Function core.time.convClockFreq

long convClockFreq (
  long ticks,
  long srcTicksPerSecond,
  long dstTicksPerSecond
) pure nothrow @nogc @safe;

ticksToNSecs

Example

// one tick is one second -> one tick is a hecto-nanosecond
writeln(convClockFreq(45, 1, 10_000_000)); // 450_000_000

// one tick is one microsecond -> one tick is a millisecond
writeln(convClockFreq(9029, 1_000_000, 1_000)); // 9

// one tick is 1/3_515_654 of a second -> 1/1_001_010 of a second
writeln(convClockFreq(912_319, 3_515_654, 1_001_010)); // 259_764

// one tick is 1/MonoTime.ticksPerSecond -> one tick is a nanosecond
// Equivalent to ticksToNSecs
auto nsecs = convClockFreq(1982, MonoTime.ticksPerSecond, 1_000_000_000);
