Falsehoods programmers believe about time
There are always 24 hours in a day.
Months have either 30 or 31 days.
Years have 365 days.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).
A week always begins and ends in the same month.
A week (or a month) always begins and ends in the same year.
The machine that a program runs on will always be in the GMT time zone.
Ok, that’s not true. But at least the time zone in which a program has to run will never change.
Well, surely there will never be a change to the time zone in which a program hast to run in production.
The system clock will always be set to the correct local time.
