Show the clock in the panel

Controls whether the clock indicator appears in the panel or not.

Controls the time format that is displayed in the indicator. For almost all users this should be the default for their locale. If you think the setting is wrong for your locale please join or talk to the translation team for your language. If you just want something different you can adjust this to be either 12 or 24 time. Or, you can use a custom format string and set the custom-time-format setting.

The format string passed to strftime

The format of the time and/or date that is visible on the panel when using the indicator. For most users this will be a set of predefined values as determined by the configuration utility, but advanced users can change it to anything strftime can accept. Look at the man page on strftime for more information.

Show the number of seconds in the indicator

Makes the datetime indicator show the number of seconds in the indicator. It's important to note that this will cause additional battery drain as the time will update 60 times as often, so it is not recommended. Also, this setting will be ignored if the time-format value is set to custom.
