That tool would be ntpd.
Just add all the servers you want to monitor, restart ntp and then run ntpq -p to see them all lined up.
You can log the data to peerstats files to a file and make long term plots.

The ntpdate  version I use seems to come from the ntp.org
package , apparently developed by the developers of the NTP
Ordinarily, ntpdate(8) is used to set the system's clock to the
time obtained by (AIUI) averaging (with weights) the times
reported by the servers specified. However, when started as
follows, it can show the difference without setting time:
$ /usr/sbin/ntpdate -uvq 0.debian.pool.ntp.org 1.debian.pool.ntp.org ...
And if the debugging mode is also set (with -d), it shows the
individual times reported, too.
