Get remotetime via commandline, set it to local clock with TZ

I was experimenting with the clock. Changed it on local box. After that, Google and other SSL websites stopped working so I was not able to get the exact local time (I don't wear a watch). Luckily, the phone was in another room so I fetched it and then set the time.

But what about automation, and times when I am in a data center where they don't allow phones? Is there a command-line way to query a non-SSL remote location to get UTC time?

Cherry would be for a tool that takes your local time zone and sets the local time, but that I can do too, only will be off a few seconds... but can adjust that by repeated

date -s "xxx" calls till it's accurate.

I looked at How to get date&time using curl command?, but when I use ntpq -c 'rv 0 clock' 139.59.15.185, I get the following output:

139.59.15.185: timed out, nothing received

***Request timed out

and the command:

ntpq -c 'rv 0 clock' ntp.ubuntu.com

outputs:

ntp.ubuntu.com: timed out, nothing received

***Request timed out

Here are the contents of sudo nano /etc/ntp.conf:

# /etc/ntp.conf, configuration for ntpd; see ntp.conf(5) for help

ntpq command is for querying the NTP server's status and configuration, not for querying time. The server probably doesn't allow to query its status from random clients, so you get timeouts. To query time from remote server, use ntpdate command:

ntpdate -q ntp.ubuntu.com

will show the time difference between your local system and the ntp.ubuntu.com server, for example:

15 Jul 18:50:09 ntpdate[25028]: adjust time server 91.189.89.198 offset -0.139723 sec

To set local time to time announced by ntp.ubuntu.com server, use:

sudo ntpdate ntp.ubuntu.com

("sudo" is needed because setting the system time requires root privileges)

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
