Maybe using a new magic number for TSE would be a cleaner solution:
"-3" = use timestamp of record that TSEL points to.
That would make things a lot more obvious and autoSaveRestore would
just work.

Dear fellow core-talkers,

Would that work? Or am I missing something?

I'm not sure how that could work.

Currently the pvlOptTSELisTime bit is set by recGblTSELwasModified() being called after the link is initialized either from iocInit.c's doResolveLinks() or from dbAccess.c's dbPutFieldLink(). At runtime if recGblGetTimeStamp() sees the bit set it does not read TSE from TSEL but just reads the timestamp through it instead.

I was thinking about using TSE=-3 instead of the pvlOptTSELisTime bit, explicitly showing the mechanism used to fetch the stamp.

But your fix is simpler and practically does the same. Excellent!

Thanks a lot,
~Ralph
