class SemanticLogger::Formatters::Base

def self.build_time_format(precision = PRECISION)

Default: PRECISION (6, except on older JRuby, where 3)
How many fractional digits to log times with.
precision: [Integer]
Parameters

Return default time format string 
def self.build_time_format(precision = PRECISION)
  "%Y-%m-%d %H:%M:%S.%#{precision}N"
end

def format_time(time)

Return the Time as a formatted string 
def format_time(time)
  time = time.dup
  case time_format
  when :rfc_3339
    time.utc.to_datetime.rfc3339
  when :iso_8601
    time.utc.iso8601(precision)
  when :ms
    (time.to_f * 1_000).to_i
  when :none
    time
  when :seconds
    time.to_f
  when :notime
    ""
  else
    time.strftime(time_format)
  end
end

def initialize(time_format: nil,

Default: PRECISION (6, except on older JRuby, where 3)
How many fractional digits to log times with.
precision: [Integer]
Default: true
Whether or not to include application name in logs
log_application: [Boolean]
Default: true
Whether or not to include hostname in logs
log_host: [Boolean]
Default: '%Y-%m-%d %H:%M:%S.%N'
:notime Returns an empty string for time ( no time is output ).
:ms Output in miliseconds since epoch.
:iso_8601 Outputs an ISO8601 Formatted timestamp.
See Time#strftime for the format of this string.
