Hi,
I understand that the ls command with "-l" option generates the "last modified time" of specific directory.
However, some generated results displayed the "last modified time" with detail about the last modified year, for example:

datetime - convert between TAI labels and seconds
SYNTAX
#include <datetime.h>
void datetime_tai(&dt,t);
datetime_sec datetime_untai(&dt);
struct datetime dt;
datetime_sec t;
DESCRIPTION
International Atomic Time, TAI, is the fundamental unit for time measurements. TAI has one label for every second of real time, without
complications such as leap seconds.
A struct datetime variable, such as dt, stores a TAI label. dt.year is the year number minus 1900; dt.mon is the month number, from 0
(January) through 11 (December); dt.mday is the day of the month, from 1 through 31; dt.hour is the hour, from 0 through 23; dt.min is the
minute, from 0 through 59; dt.sec is the second, from 0 through 59; dt.wday is the day of the week, from 0 (Sunday) through 6 (Saturday);
dt.yday is the day of the year, from 0 through 365.
The datetime library supports more convenient TAI manipulation with the datetime_sec type. A datetime_sec value, such as t, is an integer
referring to the tth second after the beginning of 1970 TAI. The first second of 1970 TAI was 0; the next second was 1; the last second of
1969 TAI was -1. The difference between two datetime_sec values is a number of real-time seconds.
datetime_tai converts a datetime_sec to a TAI label.
datetime_untai reads a TAI label (specifically dt.year, dt.mon, dt.mday, dt.hour, dt.min, and dt.sec) and returns a datetime_sec.
