Below line will produce report Report_Inventory.html showing the list of technology patches applied to 4 components (see Oracle Doc ID 1355068.1) in the instance. But it does not have timestamp for any WebLogic patches.
$ $ADPERLPRG $FND_TOP/patch/115/bin/TXKScript.pl -script=$FND_TOP/patch/115/bin/txkInventory.pl -txktop=$APPLTMP -outfile=$APPLTMP/Report_Inventory.html
bsu.sh does not give timestamp as well, and it even does not create a log file. So, below does not help on date tracking.
$ bsu.sh -report -bea_home=$FMW_HOME -output_format=text
Oracle Support says bsu.sh will be replaced by opatch to allow date tracking in the future development of technology stack, and asks to check Oracle EBS Tech blog and Doc ID 3000000.1.
