The rest of the timestamps that bypassed the time provider (#304) - #312
Conversation
Items 2 to 4 of #304; the history handlers were #310. The dashboard's stale-message threshold on all three transports that have one. Staleness is the age of a heartbeat the transport wrote, so a cut-off taken from whichever machine is asking measures the gap between two clocks as well as the age. Redis computed it through DateTimeOffset.UtcNow, which is why a search for DateTime.UtcNow missed it. The history retention cut-off in ClearHistoryMonitor, which is the worst of these: it is compared directly against stored timestamps, so a difference between the clocks moves the retention window by that difference. BaseMonitor.LastRunUtc, shown on the dashboard beside timestamps the transport wrote; the Memory transport's QueuedDateTime; and LiteDB's send, receive, heartbeat, error-move and the three find/reset queries. LiteDB is embedded, so its configured provider is normally the local clock anyway - but these values are stored and compared against each other, and going around the provider is how they stop agreeing. Two places keep DateTime.UtcNow on purpose. JobScheduler logs the scheduler's time from the provider and the local time on the next line, which is a deliberate comparison and says nothing if both sides are the same clock. The trace decorator and the dashboard web services measure spans and request timing rather than queue data, which is where the issue left them. The unit tests for the monitors, DataStorage and the three dashboard handlers constructed these directly, so they are on a fixed clock now; the relational one asserts @ThresholdTicks is derived from it.

…s it produces Review round on #312. Every constructor given an IGetTimeFactory called Create() on it before Guard.NotNull ran, so a null factory produced a NullReferenceException where the rest of the library raises ArgumentNullException. Fixed in the thirteen constructors this branch added it to, and in the four from #310 that shipped with the same ordering. The expiry query read the clock inside the LiteDB Where expression. A probe against LiteDB 5 shows it translates the call and honours the value - a row dated 2029 comes back against a clock fixed at 2030, which the machine clock would not have matched - so the reported failure does not occur. Hoisted anyway: one reading for the whole sweep is what is meant, and it matches the sibling handlers. Two changed values had a fixed clock injected but nothing asserting it, which is a test that cannot fail for the reason it exists. BaseMonitor.LastRunUtc now has one, and ClearHistoryMonitor's retention cut-off has its first test at all - that one is compared directly against stored timestamps, so a wrong clock moves the retention window rather than merely displaying an odd date. Both fail if the production code goes back to DateTime.UtcNow. Still not asserted: the LiteDB and Redis stale cut-offs, and the Memory transport's QueuedDateTime. Each needs a real database, a Redis server, or the Memory dashboard query, so the unit projects can only cover construction; the honest home is an integration test.

Pushed. Guard ordering (qodo 3 / CodeRabbit ×2) — valid. Every constructor given an Expired messages remain (qodo 1, High) — does not reproduce. I probed LiteDB 5 with the exact shape in the handler — an interface-typed field on private readonly IGetTime _getTime = new FixedTime(); // fixed at 2030
col.Insert(new Row { ExpirationTime = new DateTime(2029, 1, 1) }); // NOT expired by the machine clock
col.Query().Where(x => x.ExpirationTime < _getTime.GetCurrentUtcDate()).ToList(); // returns the rowLiteDB translates the call and uses the provider’s value — the 2029 row comes back against the 2030 clock, which the machine clock would not have matched. So expiration cleanup neither throws nor silently stops. That also matches the 115/115 LiteDB integration run, which includes Hoisted it into a local anyway: one reading for the whole sweep is what is meant, and it matches the sibling handlers. Not presented as a bug fix. Missing assertions (qodo 2) — valid, and partly addressed. Two changed values had a fixed clock injected with nothing asserting it, which is a test that cannot fail for the reason it exists:
Both fail if the production code goes back to Still not asserted, and I would rather say so than add a test that only re-checks construction: the LiteDB and Redis stale cut-offs and the Memory transport’s Validated: |

Filed as #313 rather than adding it here. The gap is real but it is a different piece of work from this PR: asserting a stale cut-off needs a message held in #313 records the non-obvious part so it stays a small task: a clock fixed in the past cannot distinguish the two sources for a stale query, because nothing is stale under either. It has to be fixed in the future — at 2030 with a 120s threshold a heartbeat written moments ago is older than the cut-off and comes back, while under the machine clock it is not and nothing comes back. It also carries the #310 lesson that the override must be on |

Items 2 to 4 of #304. The history handlers were #310; this is the rest, and it closes the issue.
IGetTimeis registered per transport — the database server's clock on SQL Server and PostgreSQL, the Redis server's on Redis — and code callingDateTime.UtcNowsilently opts out of whatever the user chose.What changed
ClearHistoryMonitor)BaseMonitor.LastRunUtcDataStorage.QueuedDateTimeRedis computed its threshold through
DateTimeOffset.UtcNow, which is why a search forDateTime.UtcNowalone did not list it.Where to look
Two places keep
DateTime.UtcNowdeliberately, and are the only judgement calls here:JobSchedulerlogs the scheduler's time from the provider and the local time on the next line. That is a deliberate side-by-side comparison; converting it would print the same value twice and say nothing.Tests
The unit tests for the monitors,
DataStorageand the three dashboard handlers constructed these types directly, so they now run on a fixed clock; the relational one asserts@ThresholdTicksis derived from it rather than from the machine.Validated locally:
Release -p:CI=true; unit suites 1192 / 277 / 198 / 183 / 242 / 36 / 222; LiteDB integration 115/115, which is the transport this touches most. Memory and Dashboard API integration are left to Jenkins.🤖 Generated with Claude Code
