Axapta 3.0 and AX 4.0 store batch and cleanup times as a local date plus
seconds. They were turned into UTC with the SQL Server's offset at collection
time, so every time from the other side of a DST change was an hour off (a job
planned 01:50 CET on the spring night looked 70 minutes late at 03:00 CEST),
and a SQL Server running UTC behind a CET AOS shifted every time.
AxLocalTime converts with the rules of the AX time zone on that date:
SQLInsight:DynamicsAx:LocalTimeZone (Windows or IANA id), else the agent's own
zone when its offset matches the SQL Server's, else the server's offset (to the
nearest quarter hour) with a Danish data note. The skipped spring hour and the
repeated autumn hour get standard time (deterministic, never throws, never a
false "late"); seconds outside 0..86400 are unknown and 86400 is midnight. The
AX 3.0 cleanup time is local by version, also when LATESTCLEANTIME is missing.
AX 2009+ UTC times are untouched. Also: remaining numbers cannot overflow for
HIGHEST = Int64.MaxValue, and run keys use the invariant culture.

The detector looks again every 5 minutes at an AX database where the agent
lacks part of the read access, so a GRANT takes effect quickly. The AX SQL
test checks that only standard AX tables are read. The hub end-to-end test
expects no AX rule outcomes without the opt-in. Docs: what 1.5's synthetic
AX checks can reuse.

docs/dynamics-ax.md: detection, the optional read access per version, how
AX is read (SELECT only, TOP, 2 s lock timeout or snapshot, never NOLOCK),
the rules SQLI-AX-001..010 with thresholds, batch times and the unverified
AX 3.0 STATUS mapping, forecasts from SQLInsight's own samples, AX users
behind blocking (CONTEXT_INFO, honest for 3.0), the hub opt-in, the API and
how to drop in a real 2009/2012 schema. AX 2009/2012/F&O are marked as based
on Microsoft's documented schema, not verified against customer data.
