Feature [?] of Soft Timestamp support

[Ralph Lange <ralph.lange@gmx.de>]

I am puzzled:

Base's devTimestamp.c provides "Soft Timestamp" support for ai and stringin records.

However,

• the stringin version converts to the POSIX epoch when producing a time string in VAL based in the format in INP, while
• the ai version converts the plain EPICS time stamp (using the EPICS epoch) to a double VAL.

Is that on purpose?
If yes, what purpose?

Thanks a lot,
