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 end
Public Instance Methods
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
Returns fractional seconds, or 0 if not set.
# File lib/dbi/utils/timestamp.rb, line 55 def fraction @fraction || 0 end
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
