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.
