Implementation Strategies

1. Technical Time Zone Handling

  • Store all promotion times in UTC
  • Use server-side libraries for precise conversions
  • Implement timezone detection via user's browser/IP

2. User Experience Considerations

  • Display times in user's local timezone
  • Include timezone indicator (e.g., 'EST', 'PST')
  • Provide clear start and end times

Promotion Time Zone Best Practices

Do's

  • Use 24-hour format for clarity
  • Explicitly state timezone for promotions
  • Test timezone conversions thoroughly

Don'ts

  • Avoid ambiguous time representations
  • Don't rely on client-side time calculations
  • Never assume a single timezone

Code Example: Time Zone Conversion

// Pseudo-code for timezone handling
function convertPromotionTime(promotionTime, userTimezone) {
  const utcTime = convertToUTC(promotionTime)
  const localTime = convertToTimezone(utcTime, userTimezone)
  return formatLocalTime(localTime)
}
