DBI::Timestamp(year=0,month=0,day=0,hour=0,min=0,sec=0,fraction=nil) DBI::Timestamp(Time) DBI::Timestamp(Date)

Creates and returns a new DBI::Timestamp object. This is similar to a Time object in the standard library, but it also contains fractional seconds, expressed in nanoseconds. In addition, the constructor accepts either a Date or Time object.

# File lib/dbi/utils/timestamp.rb, line 21
def initialize(year=0, month=0, day=0, hour=0, min=0, sec=0, fraction=nil)
   case year
      when ::Time
         @year, @month, @day = year.year, year.month, year.day 
         @hour, @minute, @second, @fraction = year.hour, year.min, year.sec, nil 
         @original_time = year
      when ::Date
         @year, @month, @day = year.year, year.month, year.day 
         @hour, @minute, @second, @fraction = 0, 0, 0, nil 
         @original_date = year
      else
         @year, @month, @day = year, month, day
         @hour, @minute, @second, @fraction = hour, min, sec, fraction
   end

Public Instance Methods

==(timestamp) click to toggle source

Returns true if timestamp has a year, month, day, hour, minute, second and fraction equal to the comparing object.

Returns false if the comparison fails for any reason.

# File lib/dbi/utils/timestamp.rb, line 45
def ==(timestamp)
   @year == timestamp.year and @month == timestamp.month and
   @day == timestamp.day and @hour == timestamp.hour and
   @minute == timestamp.minute and @second == timestamp.second and
   (fraction() == timestamp.fraction)
rescue
   false
end
fraction() click to toggle source

Returns fractional seconds, or 0 if not set.

# File lib/dbi/utils/timestamp.rb, line 55
def fraction
   @fraction || 0
end
to_date() click to toggle source

Returns a new Date object based on the year, month and day or, if a Date object was passed to the constructor, returns that object.

# File lib/dbi/utils/timestamp.rb, line 92
def to_date
   @original_date || ::Date.new(@year, @month, @day)
end
to_s() click to toggle source

Returns a DBI::Timestamp object as a string in YYYY-MM-DD HH:MM:SS format. If a fraction is present, then it is appended in “.FF” format.

# File lib/dbi/utils/timestamp.rb, line 71
def to_s
   string = sprintf("%04d-%02d-%02d %02d:%02d:%02d",
       @year, @month, @day, @hour, @minute, @second) 

   if @fraction
      fraction = ("%.9f" % (@fraction.to_i / 1e9)).
                  to_s[1..-1].gsub(/0{1,8}$/, "")
      string += fraction
   end

   string
end
to_time() click to toggle source

Returns a new Time object based on the year, month and day or, if a Time object was passed to the constructor, returns that object.

# File lib/dbi/utils/timestamp.rb, line 86
def to_time
   @original_time || ::Time.local(@year, @month, @day, @hour, @minute, @second)
end
