In SRO reporting, how often are Time of Receipt (TOR) updates received?

• A. Every 60 minutes
• B. Every 15 minutes
• C. Every 55 minutes
• D. Every 90 minutes

Answer: (C)

The key idea is how often TOR (Time of Receipt) updates are produced in SRO reporting. TOR reflects when a report is actually received, and updates are issued on a fixed cycle so you have near‑real‑time visibility without overwhelming the system with constant updates. In this setup, TOR updates occur about every 55 minutes. That cadence keeps the information fresh enough for tracking and SLA monitoring, while reducing the overhead that would come with more frequent updates.

If it helps to contrast, updating every 60 minutes would be a clean hourly mark, which is slower visibility; updating every 15 minutes would flood the system with updates and unnecessary noise; and waiting 90 minutes would lag too long for timely tracking. The 55‑minute interval strikes a balance, providing timely yet manageable updates.
