Method: String#to_time

Defined in:
lib/active_support/core_ext/string/conversions.rb

#to_time(form = :local) ⇒ Object

Converts a string to a Time value. The form can be either :utc or :local (default :local).

The time is parsed using Time.parse method. If form is :local, then the time is in the system timezone. If the date part is missing then the current date is used and if the time part is missing then it is assumed to be 00:00:00.

"13-12-2012".to_time               # => 2012-12-13 00:00:00 +0100
"06:12".to_time                    # => 2012-12-13 06:12:00 +0100
"2012-12-13 06:12".to_time         # => 2012-12-13 06:12:00 +0100
"2012-12-13T06:12".to_time         # => 2012-12-13 06:12:00 +0100
"2012-12-13T06:12".to_time(:utc)   # => 2012-12-13 06:12:00 UTC
"12/13/2012".to_time               # => ArgumentError: argument out of range
"1604326192".to_time               # => ArgumentError: argument out of range
