Description
The time command lets you specify the time format for any log or group. If no label is specified, this command sets a global default value for all logs and groups. Any specific value always overrides the global definition, regardless of the order in the configuration file or when a command is sent.
You can prepend any printf-style format modifiers to the time spec field names, as appropriate for the field type. Some of these format modifiers will be ignored (e.g., %y and %Y ignore format modifiers). The string-type fields, %J and %M, respond to %s modifiers.
 | Sub-second fields (%T, %L, %U, %N) usually need to be zero-padded to produce readable results, as in %z.%09N. |
