Time zones, abbreviations, and becoming grumpy with age

I'm 40 years old now, and I can feel my list of annoyances growing as I age. If I'm not careful, by the time I'm 80, I'll be one of those people Meg Ryan's character described in French Kiss.

The way people abbreviate time zones is often wrong. I live in the Central Time zone in the United States. Depending on the time of year, you abbreviate it in one of two ways.
  • CST: Central Standard Time
  • CDT: Central Daylight Time
In the United States, we have Daylight savings time between early/mid March and early November (see chart), and Standard time the rest of the year. Can you tell what's wrong with this sentence?
The meeting will be held at 14:00 CST on July 8.
Answer: There is no CST on July 8, there is only CDT. Perhaps I have an unfair advantage over the general public, because as a computer network engineer, I have to manage devices where you specify CDT verses CST as far as how you name the time zones.

Anyway, the dirty secret is that the very things that drive me nuts about other people, I sometimes do myself! Once in a while, I fall victim to not catching my own grammer or spellling mistakes [intentionally ironic]. I guess when Jesus said...
“Do not judge, or you too will be judged. For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you” (Matthew 7:1-2).
... he wasn't just teaching a good truth, he was (and is) trying to protect us from opening up judgement on ourselves (i.e., looking stupid)!
