In Ruby, what is good way to filter all the methods of an object that contain the word "time" in it?

I tried the following and it was partly working:
>> s.methods.map {|n| n if n =~ /time/}
=> [nil, nil, nil, nil, nil, nil, nil, nil, "skip_time_zone_conversion_for_attri
butes", nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, ni
l, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, ni
l, "timestamped_migrations", nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, n
il, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, n
il, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, n
il, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, n
il, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, "time_zone_aware
_attributes", nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, nil, n

"skip_time_zone_conversion_for_attributes"
"timestamped_migrations"
