Re: Does environment variable QIBM_QBASEYEAR affect timestamp variables?

[Rob Berendt <robertowenberendt@xxxxxxxxx>]

Definitive answer from IBM as posted in my case:

"IBM development answered that system date functions only extend to the
system date range of 2069.

Since the DISPLAY_JOURNAL function uses the QjoRetrieveJournalEntries API,
and that API uses system date functions, the developer says that any date
past 2069 would be unreliable. "
