Sorry for not answering this right away. I was on vacations. I investigated some date tests and found that in some of them (http://compute1.aar:9013/golem/date-parse.html) more then 80% of time is taken by determining the DST offset.
I'm working right now to eliminate system call to check DST offset at all, caching it when possible. My CL: http://codereview.chromium.org/1758013/show Anders, what do you think we should do? Check for DST offset on each time? Check from time to time (once a minute or so)? Do not check at all?
