The code shown will result in a timer pop at 11:00:00 local time. As to when the code will get control to issue the STCKE, that is a question of system dispatching and priorities.
>From a dump, I think you will be able to see the external interrupt clock comparator timer pop, at whatever STCK(E) time corresponds to 11:00:00 local time. STCKCONV does not do "local time". While it seems unlikely, if you are finding the result off by a minute, since CVTLSO is 0's, perhaps your timezone offset is set to 1 minute off from the number of hours you expect. check CVTLDTO (although the system is using a different block than that when working with timezone offset and leap seconds; the corresponding areas are expected to match).
