ntpdate 1:4.2.8p11+dfsg-1ubuntu1 (ppc64el binary) in ubuntu cosmic

 NTP, the Network Time Protocol, is used to keep computer clocks
 accurate by synchronizing them over the Internet or a local network,
 or by following an accurate hardware receiver that interprets GPS,
 DCF-77, NIST or similar time signals.
 .
 ntpdate is deprecated. Please use sntp instead for manual or scripted
 NTP queries/syncs.
 .
 Historically this package also includes hooks for ifupdown and dhclient.
 These will be migrated to sntp in the future. If the full NTP daemon from
 the package "ntp" is installed, this package is not necessary and may cause
 unwanted behaviour.
