Darrold,
Thanks for the tip.
About three milliseconds after I sent my email it occurred to me I could
compare SMF121JRS_STRTTME to SMF121TME (time the record moved into the SMF
buffer). It turns out that SMF121JRS_STRTTME plus the JVM elapsed time
(SMF121JRS_UPTIME) is four hours ahead of SMF121TME which is the GMT offset for
EDT.
Again, thanks and sorry about the thrash.
