Serialize a TimeSpan type.

IMPORTANT: Set your MonoBehaviour/ScriptableObject to partial if the field is declaration inside. If it's inside a normal class/struct, you need to set all parent class/struct to partial

using SaintsField;

// note the partial
public partial class SerTimeSpanExample : MonoBehaviour
{
    [SaintsSerialized]
    private TimeSpan _dt;

    [SaintsSerialized]
    private List<TimeSpan> _dtList;
}

// use in a normal class/struct, set parents partial recursively
public partial class SerTimeSpanExample : MonoBehaviour
{
    [Serializable]
    public partial class MyClass
    {
        [SaintsSerialized]
        private TimeSpan[] _dtArray;
    }

    // No SaintsSerialized here
    public MyClass myClass;
}
