this is usually the case when epoch (expressed in microseconds) turns to adulthood.
year = epoch / 1000 / 1000 / 60 / 60 / 24 / 365
but leap years have 366 days, so isn"t it inaccurate to divide by 365?
I"m just going to give you an example. Does a leap year have an impact on which step of the time transition? is it inaccurate to convert epoch to a unit smaller than the day?
-sharpinclude<stdio.h>
-sharpinclude<time.h>
int main()
{
time_t ts = time(NULL);
tm* time_obj = localtime(&ts);
printf("%d", time_obj->tm_year + 1900);
} solar year is 365.24 * 86400s
the "calendar / local time" stipulated by human beings has many complicated factors: https://github.com/kdeldycke/... 's own implementation is mostly problematic
