Dates and Times

Format

Dates and times are displayed as stipulated by the ISO Standard 8601. They are indicated in UTC.

  • Dates are written: YYYY-MM-DD. Example: 2021-04-07

  • Then follows T (for time) as a separator between date and time Example: 2021-04-07T

  • Times are written: hh:mm:ss Example: 2021-04-07T13:16:00

  • Then follows recommended information, the difference to the coordinated universal time (UTC). It is written: +hh:mm Example: 2021-04-07T13:16:00+01:00

DENIC uses this format for all services. Thus, also times and dates in messages of INFO and whois outputs etc. are displayed in this format

Time Servers of DENIC

DENIC operates two time servers that can be used via NTP (Network Time Protocol (Version 3)) for synchronization. Only NTP version 3 is supported:

ntp1.denic.de

ntp2.denic.de

A server with realtime clock gives the servers the actual time. If this time source is not available due to failure, the servers synchronize with the NTP server of the metrology institute Physikalisch-Technische Bundesanstalt Braunschweig.
