Dear Concordia University,

I am writing to you on behalf of the Concordia student body regarding the final exams and the decision to use online proctoring. We are urging you to change your decision about having online proctored exams. For many, this is an appalling invasion of privacy, a security risk, a demand for students to trade their morals for a grade, and discrimination against the less fortunate among the student body. In addition, over 7000 thousand Concordia students are against online proctoring.

Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

There are always 24 hours in a day.
February is always 28 days long.
Any 24-hour period will always begin and end in the same day (or week, or month).
