Falsehoods programmers believe about time, in a single list

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).

fun gzip(content: String): ByteArray {
val bos = ByteArrayOutputStream()
GZIPOutputStream(bos).bufferedWriter(UTF_8).use { it.write(content) }
return bos.toByteArray()
