Thanks, the scalar of localtime works, with a decimal correctly placed:
My real problem is with the Oracle trace data. It has a time value in microseconds since the epoch, but the conversion appears to be off by 9 months. The print statement above is from September 2004, but the conversion lands in November 2003. As in the following source data:
*** SESSION ID:(92.34308) 2004-09-06 11:52:07.103
APPNAME mod='sqlplus@prod90db (TNS V1-V3)' mh=0 act='' ah=0
PARSING IN CURSOR #1 len=69 dep=0 uid=0 oct=42 lid=0 tim=1068837428812
It's time to read the Oracle docs again!!
