If no configuration options are provided, pattern-config is
employed. There JsonTemplateLayoutDefaults.getTimestampFormatPattern(), JsonTemplateLayoutDefaults.getTimeZone(), JsonTemplateLayoutDefaults.getLocale() are used as defaults for
pattern, timeZone, and locale, respectively.
In epoch-config, millis.nanos, secs.nanos stand
for the fractional component in nanoseconds.
