clockspeed uses a hardware tick counter to compensate for a persistently fast or slow system clock. Given a few time measurements from a reliable source, it computes and then eliminates the clock skew. sntpclock checks another system's NTP clock and prints the results in a format suitable for input to clockspeed. sntpclock is the simplest available NTP/SNTP client. taiclock and taiclockd form an even simpler alternative to SNTP. They are suitable for precise time synchronization over a local area network, without the hassles and potential security problems of an NTP server.
mess822 is a fast library for parsing Internet mail messages, with several qmail-compatible applications. It supports the full complexity of RFC 822 address lists and common RFC 822 extensions, and extracts each address as an easy-to-use string, with a separate string for the accompanying comment. mess822 also converts RFC 822 dates into libtai's struct caltime format, with support for numeric time zones, the standard old-fashioned time zones, and many nonstandard time zones.
