Remarks

This class behaves just like a Double representing a time in seconds; it is implicitly castable to and from a Double and therefore can be generally used "as" a double, but it has the advantage of handling conversions to and from other time representations, specifically minutes, hours, days, weeks, atomic units of time, Planck time and ke. Metric conversions are handled simply by applying the needed SI conversion factor, for example:

Example

Convert time in nanoseconds to seconds:

Copy

public Time GetSeconds(double nanoseconds)
{
    return nanoseconds * SI.Nano;
}

Convert time in seconds to milliseconds:

Copy

public double GetMilliseconds(Time seconds)
{
    return time / SI.Milli;
}

This example converts minutes to hours:

Copy

public double GetHours(double minutes)
{
    return Time.FromMinutes(minutes).ToHours();
}

Note that the ToString method will convert the Time value, in seconds, into a textual representation of years, days, hours, minutes and seconds using the static function ToElapsedTimeString(Double, Int32, String, Double).
