Another rather small change that was introduced to Solaris 11 in SRU 66. Up to SRU 65 the precision of the timestamps in the logfile was seconds.

However, since SRU 66 Solaris provides fractional timestamps:
Jul 5 09:44:22.030 testbed genunix: [ID 540533 kern.notice] SunOS Release 5.11 Version 11.4.70.170.1 64-bit
Jul 5 09:44:22.030 testbed genunix: [ID 473128 kern.notice] Copyright (c) 1983, 2024, Oracle and/or its affiliates.
Furthermore, the precision can be changed by the properties of an SMF service.
root@testbed:/var/adm# svccfg -s svc:/system/system-log:default setprop config/time_precision = integer: 5
root@testbed:/var/adm# svcadm refresh svc:/system/system-log:default
After this change, the timestamps will have 5 digits in the fractional part of the timestamp.
Jul 25 15:23:51.24155 testbed genunix: [ID 936769 kern.notice] ramdisk1024 is /pseudo/ramdisk@1024
Jul 25 15:23:51.25119 testbed isa: [ID 202937 kern.notice] ISA-device: pit_beep0
In addition to this change, the timestamp format has been changed to enable logging beyond January 2038.
