### toTimeString

    public static String toTimeString(long seconds)

  Parameters:
    `seconds` - The number of seconds to convert.
  Returns:
    A string representing hours, minutes, seconds, e.g. `11:23:44`

### fromTimeString

    public static long fromTimeString(String s)

  Parameters:
    `s` - A string representing hours, minutes, seconds, e.g. `11:23:44`
