Uses Date to provide precise Time calculations for years, months, and days. The options parameter takes a hash with any of these keys: :years, :months, :weeks, :days, :hours, :minutes, :seconds.

Returns a new Time representing the time a number of seconds ago, this is basically a wrapper around the Numeric extension

Alias for beginning_of_month

Alias for beginning_of_quarter

Alias for beginning_of_week

Alias for beginning_of_year

Alias for end_of_month

Alias for end_of_quarter

Alias for end_of_week

Returns a new Time representing the start of the day (0:00)

Returns a new Time representing the start of the month (1st of the month, 0:00)

Returns a new Time representing the start of the quarter (1st of january, april, july, october, 0:00)

Returns a new Time representing the "start" of this week (Monday, 0:00)

Returns a new Time representing the start of the year (1st of january, 0:00)

Returns a new Time where one or more of the elements have been changed according to the options parameter. The time options (hour, minute, sec, usec) reset cascadingly, so if only the hour is passed, then minute, sec, and usec is set to 0. If the hour and minute is passed, then sec and usec is set to 0.

Layers additional behavior on Time#<=> so that DateTime and ActiveSupport::TimeWithZone instances can be chronologically compared with a Time

Returns a new Time representing the end of the day (23:59:59)

Returns a new Time representing the end of the month (last day of the month, 0:00)

Returns a new Time representing the end of the quarter (last day of march, june, september, december, 23:59:59)

Returns a new Time representing the end of this week (Sunday, 23:59:59)

Returns a new Time representing the end of the year (31st of december, 23:59:59)

Tells whether the Time object‘s time lies in the future

Alias for since

Short-hand for months_ago(1)

Short-hand for years_ago(1)

Alias for beginning_of_day

Time#- can also be used to determine the number of seconds between two Time instances. We‘re layering on additional behavior so that ActiveSupport::TimeWithZone instances are coerced into values that Time#- will recognize

Alias for beginning_of_week

Returns a new Time representing the time a number of specified months ago

Returns a new Time representing the time a number of specified months in the future

Short-hand for months_since(1)

Returns a new Time representing the start of the given day in next week (default is Monday).

Short-hand for years_since(1)

Tells whether the Time object‘s time lies in the past

Seconds since midnight: Time.now.seconds_since_midnight

Returns a new Time representing the time a number of seconds since the instance time, this is basically a wrapper around the Numeric extension.

Tells whether the Time object‘s time is today

Convenience method which returns a new Time representing the time 1 day since the instance time

Returns a new Time representing the time a number of specified years ago

Returns a new Time representing the time a number of specified years in the future

Convenience method which returns a new Time representing the time 1 day ago
