Quick answers

Why are timezone abbreviations risky?

Some abbreviations are reused by different regions. CST can mean Central Standard Time, China Standard Time, or Cuba Standard Time.

What should I use instead of an abbreviation?

Use a city or IANA timezone when possible, such as America/Chicago, Asia/Shanghai, or Europe/London.
