Clears the time portion of this Date instance; useful utility where it makes sense to compare month/day/year only portions of a Date.
Support creating a new Date having similar properties to an existing Date (which remains unaltered) but with some fields updated according to a Map of changes.
Example usage:
import static java.util.Calendar.YEAR def today = new Date() def nextYear = today[YEAR] + 1 def oneYearFromNow = today.copyWith(year: nextYear) println today println oneYearFromNow
updates -  A Map of Calendar keys and valuesIterates from this date down to the given date, inclusive, decrementing by one day each time.
to -       another Date to go down toclosure -  the closure to callCreate a String representation of this date according to the given format pattern.
For example, if the system timezone is GMT,
new Date(0).format('MM/dd/yy') would return the string
"01/01/70". See documentation for SimpleDateFormat
for format pattern use.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).
format -  the format pattern to use according to SimpleDateFormatCreate a String representation of this date according to the given format pattern and timezone.
For example:
def d = new Date(0)
def tz = TimeZone.getTimeZone('GMT')
println d.format('dd/MMM/yyyy', tz)
 would return the string
"01/Jan/1970". See documentation for SimpleDateFormat
for format pattern use.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).
format -  the format pattern to use according to SimpleDateFormattz -      the TimeZone to useSupport the subscript operator for a Date.
field -  a Calendar field, e.g. MONTHReturn a string representation of the 'day' portion of this date
according to the locale-specific DateFormat#SHORT default format.
For an "en_UK" system locale, this would be dd/MM/yy.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).
Return a string representation of the date and time time portion of this Date instance, according to the locale-specific format used by DateFormat. This method uses the DateFormat#SHORT preset for the day portion and DateFormat#MEDIUM for the time portion of the output string.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).
Return a string representation of the time portion of this date
according to the locale-specific DateFormat#MEDIUM default format.
For an "en_UK" system locale, this would be HH:MM:ss.
Note that a new DateFormat instance is created for every invocation of this method (for thread safety).
Subtract a number of days from this date and returns the new date.
days -  the number of days to subtractSubtract another Date from this one and return the number of days of the difference.
Date self = Date then + (Date self - Date then)
IOW, if self is before then the result is a negative value.
then -  another DateIncrement a Date by one day.
Parse a String into a Date instance using the given pattern. This convenience method acts as a wrapper for SimpleDateFormat.
Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
format -  pattern used to parse the input string.input -   String to be parsed to create the date instanceParse a String into a Date instance using the given pattern and TimeZone. This convenience method acts as a wrapper for SimpleDateFormat.
Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
format -  pattern used to parse the input string.input -   String to be parsed to create the date instancezone -    TimeZone to use when parsingParse a String matching the pattern EEE MMM dd HH:mm:ss zzz yyyy containing US-locale-constants only (e.g. Sat for Saturdays). Such a string is generated by the toString method of Date
Note that a new SimpleDateFormat instance is created for every invocation of this method (for thread safety).
dateToString -  String to be parsed to create the date instance. Must match the pattern EEE MMM dd HH:mm:ss zzz yyyy with US-locale symbolsAdd a number of days to this date and returns the new date.
days -  the number of days to increaseDecrement a Date by one day.
Support the subscript operator for mutating a Date.
field -  A Calendar field, e.g. MONTHvalue -  The value for the given field, e.g. FEBRUARYSupport mutating a Date with a Map.
The map values are the normal values provided as the
second parameter to java.util.Calendar#set(int, int).
The keys can either be the normal fields values provided as
the first parameter to that method or one of the following Strings:
| year | Calendar.YEAR | 
| month | Calendar.MONTH | 
| date | Calendar.DATE | 
| dayOfMonth | Calendar.DATE | 
| hourOfDay | Calendar.HOUR_OF_DAY | 
| minute | Calendar.MINUTE | 
| second | Calendar.SECOND | 
import static java.util.Calendar.YEAR def date = new Date() def nextYear = date[YEAR] + 1 date.set(year: nextYear) println date
updates -  A Map of Calendar keys and valuesConvert a Date to a Calendar.
Return a java.sql.Timestamp given a java.util.Date.
Legacy alias for copyWith. Will be deprecated and removed in future versions of Groovy.
