// Example 1: January 1st, 2024 at 00:00 Paris time// Paris is UTC+1 in winter, so we need to convert to UTC (23:00 previous day)"2023-12-31T23:00:00Z"// Example 2: July 1st, 2024 at 00:00 Paris time// Paris is UTC+2 in summer (due to daylight saving), so we need to convert to UTC (22:00 previous day)"2024-06-30T22:00:00Z"
