CRITICAL FIX: Replace all DateTime.UtcNow with DateTime.Now throughout the application.
Reason: Legacy VB.NET system uses local server time, and database stores all
timestamps as local time. Using UTC breaks compatibility and causes incorrect
time comparisons.
Changes:
- EmailProcessedEvent: ProcessedDate now uses DateTime.Now
- EmailHistory.MarkAsProcessed(): ProcessedDate now uses DateTime.Now
- EmailHistory.MarkAsFailed(): ProcessedDate now uses DateTime.Now
- EmailProfile.UpdateLastPollTime(): LastPollTime now uses DateTime.Now
- EmailProfile.ShouldPoll(): Poll interval comparison now uses DateTime.Now
Documentation:
- Added critical note to agents.md about DateTime usage
- Includes examples and detailed explanation for future developers
This ensures all date/time operations remain compatible with legacy database.
