Those Who Repeat the Past -- We sent you back in time, instead of forward in FAQtoids 003. We said that the offset in mail headers from the zone formerly known as Greenwich Mean Time (GMT) is added to local time to get GMT or Universal Time (UT). The correct way to say it is that the offset is added to GMT to get local time. If you get mail that reads "05:00:00 -0700 (PDT)" in one of the headers, it means "add negative 0700 to the current GMT and you'll get 05:00:00 Pacific Daylight Time." At 5 A.M. PDT, it's noon GMT; adding negative 7 to noon gets you 5 A.M., the local time when the mail was sent. And don't get us started about springing forward or falling back. [GF]
Syslogd Overwhelming Your Computer?
If your Leopard (Mac OS X 10.5) system is unexpectedly sluggish, logging might be the culprit. Run Activity Monitor (Applications/Utilities/ folder), and click the CPU column twice to get it to show most to least activity. If syslogd is at the top of the list, there's a fix. Syslogd tracks informational messages produced by software and writes them to the asl.db, a file in your Unix /var/log/ directory. It's a known problem that syslogd can run amok. There's a fix: deleting the asl.db file.
Launch Terminal (from the same Utilities folder), and enter these commands exactly as written, entering your administrative password when prompted:
sudo launchctl stop com.apple.syslogd
sudo rm /var/log/asl.db
sudo launchctl start com.apple.syslogd
Your system should settle down to normal. For more information, follow the link.
