Just edit conf-cc and add "--include error.h" so it compiles with modern glibc packages and do a "make; make setup check". Then perform the following steps: 1. start the daemon: "# nohup /usr/local/clockspeed/bin/clockspeed &" 2. give it the current time: "# /usr/local/clockspeed/bin/sntpclock ntp.srv.ip.123 | /usr/local/clockspeed/bin/clockadd" 3. now, after a few hours give it an updated reading so it can adjust to your clock: "# at now + 8 hours at> /usr/local/clockspeed/bin/sntpclock ntp.srv.ip.123 > /usr/local/clockspeed/adjust at> ^D" 4. repeat step 3 for "+ 16 hours" and "+ 24 hours" to get a more accurate reading 5. put a small script into /etc/init.d that starts clockspeed at boottime, something like: #!/bin/sh /usr/local/clockspeed/bin/clockspeed & 6. ... [need to figure this out] 7. profit! djb has a nice tool called “clockspeed” that will slow your clock down or speed it up if needed. Just edit conf-cc and add “–include error.h” so it compiles with modern glibc packages and do a “make; make setup check”. Then perform the following steps:

1. start the daemon: “# nohup /usr/local/clockspeed/bin/clockspeed &”
2. give it the current time: “# /usr/local/clockspeed/bin/sntpclock ntp.srv.ip.123 | /usr/local/clockspeed/bin/clockadd”
3. now, after a few hours give it an updated reading so it can adjust to your clock:
“# at now + 8 hours
at> /usr/local/clockspeed/bin/sntpclock ntp.srv.ip.123 > /usr/local/clockspeed/adjust
at> ^D”

4. repeat step 3 for “+ 16 hours” and “+ 24 hours” to get a more accurate reading

5. put a small script into /etc/init.d that starts clockspeed at boottime, something like:
#!/bin/sh
/usr/local/clockspeed/bin/clockspeed &

7. profit!
