Many developers assume that using DateTime.UtcNow is enough to guarantee UTC-safe API requests. But there’s a subtle issue in .NET that can silently corrupt timestamp serialization and cause external APIs to reject perfectly valid requests. This post explores a real-world debugging scenario involving inconsistent UTC serialization, explains why it happens, and shows how to prevent it in your own applications.
