If the data for the current time are fewer than two digits (0-9,) the higher-order
digit will be padded with a zero.
If the data for the current minute are fewer than two digits (0-9,) the
higher-order digit will be padded with a zero.
If the data for the current second are fewer than two digits (0-9,) the
higher-order digit will be padded with a zero.
