convertTime function

double convertTime(Time from, Time to, double value)

Convert Time. It may lose some decimals in the proccess.

from, to and value can NOT be null, otherwise an AssertionError is thrown

Basic usage:

main() {
  final time = convertTime(
    Time.minute, // from
    Time.second, // to
    1, // value
  );
  print(temperature); // 60
}

Implementation
