Pros

• They are crucial for avoiding errors in date-time calculations, such as missed appointments or incorrect billing, and for complying with legal or business requirements that depend on accurate local time representations
• Related to: date-time-handling, utc-conversion

Cons

• Specific tradeoffs depend on your use case
