note Lhamo Latso Thanks, the scalar of localtime works, with a decimal correctly placed: <code> print scalar(localtime(1068837428.812901))."\n"; </code> <p> 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: <code> *** 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=1068837428812901 hv=... </code> <p> It's time to read the Oracle docs again!! 390711 390720
