-a always,exit -F arch=b64 -S adjtimex,settimeofday -F key=time-change
-a always,exit -F arch=b32 -S clock_settime -F a0=0x0 -F key=time-change
-a always,exit -F arch=b64 -S clock_settime -F a0=0x0 -F key=time-change
# Introduced in 2.6.39, commented out because it can make false positives
#-a always,exit -F arch=b32 -S clock_adjtime -F key=time-change
#-a always,exit -F arch=b64 -S clock_adjtime -F key=time-change
-w /etc/localtime -p wa -k time-change

## Things that could affect system locale
-a always,exit -F arch=b32 -S sethostname,setdomainname -F key=system-locale
-a always,exit -F arch=b64 -S sethostname,setdomainname -F key=system-locale
