It worked!
re=/^(.+?)\s+(end\s+at)(.+?)$/i
puts s.match(re)
result:Change image name to lower end at 2006-11-05T15:01:14+0800
$2==Change image name to lower
puts s.scan(re)
result:
Change image name to lower
end at
 2006-11-05T15:01:14+0800
Transfer dbf to SQLServer
end at
 2006-11-05T15:01:15+0800
$2==Transfer dbf to SQLServer
