Duration doesn't have any ticks. As its documentation states, it holds its time internally in hecto-nanoseconds. Its total function can be used to convert the entire Duration to whatever units you want: https://dlang.org/phobos/core_time.html#.Duration.total whereas its split function allows you to split it into whatever units you want: https://dlang.org/phobos/core_time.html#.Duration.split And simply converting a Duration to a string prints out the units with them split out in a human readable manner. e.g. writeln(usecs(502397292)); would print 8 minutes, 22 secs, 397 ms, and 292 μs https://dlang.org/phobos/core_time.html#.Duration.toString Subtracting MonoTimes specifically gives a Duration rather than a TickDuration or anything else representing the number of ticks, because you don't normally care about the number of ticks, and its cleaner to have only one duration type. Anyone who wants the number of ticks would have to use MonoTime's ticks property to get at them and then subtract those directly. So, anything holding the monotonic time now uses MonoTime to hold the times and gives the length of time as a Duration. - Jonathan M Davis
