+# 1. Dynamic Cache
+
+Date: 2023-06-14
+
+## Status
+
+Accepted
+
+## Context
+
+Use tfchain uptimeV2 instead of old deprecated v1 uptime
+
+## Decision
+
+The uptime v2 also give an `timestamp hint` which is the time when the node sent the report as per the node itself. The chain
+will then accept the report if and only if the hint is in an acceptable range of the chain local timestamp.
+
+This is to prevent reports that have been buffered (delayed) on either sides of the client or the server from still getting processed
+and causing inconsistency in the uptime report for that node.
+
+Now nodes that are going to use v2 will get an error if the report is too old (or in the future)
+
+## Consequences
