[Feature Request]: Should totalSeconds and totalMicroseconds support an optional type argument to vary their return type?

[lydia-duncan]

Summary of Feature

Description:
When discussing #26798 in the team meeting today, there was some uncertainty about the return type used for totalMicroseconds. The user requesting the feature proposed it using int and the main reason totalSeconds uses real seems to be because it must divide the number of microseconds to determine the total number of seconds used. Additionally, there were tests that had used totalSeconds similarly to how totalMicroseconds would be used and some of them explicitly cast the result to an int.

Note that since the type argument would have a default value of the type returned by the methods today, this would not be considered a breaking change on timeDelta.totalSeconds (which is otherwise considered stable) unless we decided to use a different default type for the argument.

Is this issue currently blocking your progress?
no, it was just something that occurred to us

Code Sample

use Time;

var a = new timeDelta(microseconds=10);
writeln(a.totalMicroseconds(t=real));
