Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

What others think

I don't get it to work with bash. What are the prerequisites ?

CodSpirit: On some systems, such as Debian and Debian offshoots, net redirections aren't enabled in Bash. You can do the same thing with curl, wget, or nc, though:

curl -s time.nist.gov:13 nc time.nist.gov 13 wget -q -O- time.nist.gov:13

You have to enable net-redirections when compiling bash to do it.

That doesn't work on debian derivated distros by default...

Comment by sputnick 365 weeks and 5 days ago

Works for me on Ubuntu and OS X. I do not have Debian...

Comment by drewk 365 weeks and 5 days ago

Indeed it is not enabled on Ubuntu 9.04

Thanks eightmillion for alternatives

To convert to local time, you can use the date command, thus the full command will be:

wget -q -O- time.nist.gov:13 | awk '{print $2,$3}' | grep -v "^ *$" | (read t; date "+%Y-%m-%d %H:%M:%S %Z" -d "$t +0000")

(if it needs explaining, we get the date portion, skip empty line, read into variable t, then use date to print in local time)
