Writes datetime values in the form ddmmmyy: hh: mm: ss. ss.

Category:	Date and Time
Alignment:	Right
Restriction:	If w-d <17, SAS truncates the decimal values.
Interaction:	When the DECIMALCONV = system option is set to STDIEEE, the output that is written using this format might differ slightly from previous releases. for more information, see DECIMALCONV = System Option in SAS System Options: Reference.

SyntaxDATETIMEw. d
Syntax Descriptionw

Specifies the width of the output field.

Default	16
Range	7-40
Tip	SAS requires a minimum w value of 16 to write a SAS datetime value with the date, hour, and seconds. add an additional two places to w and a value to d to return values with optional decimal fractions of seconds.

D

Specifies the number of digits to the right of the decimal point in the seconds value. This argument is optional.

Range	0-39
Requirement	Must be less than w

DetailsThe DATETIMEw. d format writes SAS datetime values in the form ddmmmyy: hh: mm: ss. ss: ddis an integer that represents the day of the month. mmm is the first three letters of the month name. yyis a two-digit integer that represents the year. hhis an integer that represents the hour in 24-hour clock time. mmis an integer that represents the minutes. ss. ssis the number of seconds to two decimal places. exampleThe example table uses the input value of 1668138559, which is the SAS datetime value that corresponds to 3:49:19 a.m. on November 10,201 2.

DATETIMEw. Timeout

SyntaxDATETIMEw. Syntax Descriptionw

Specifies the width of the input field.

Default	18
Range	13-40

DetailsThe datetime values must be in the following form: ddmmmyy or ddmmmyyyy, followed by a blank or special character, followed by hh: mm: ss. ss (the time): dd is an integer between 01 and 31 that represents the day of the month. mmmis the first three letters of the month name. yy or yyyyis a two-digit or four-digit integer that represents the year. hh is an integer between 00 and 23 that represents hours. mmis an integer between 00 and 59 that represents minutes. ss. ss is the number of seconds ranging from 00-59 with the fraction of a second following the decimal point. DATETIMEw. requires values for both the date and the time. however, the ss. ss portion is optional. note: SAS interprets a two-digit year as belonging to the 100-year span that is defined by the YEARCUTOFF = system option. note: SAS can read time values with AM and PM in them. comparisonsThe DATETIMEw. d Required reads datetime values with optional separators in the form dd-mmm-yy Hh: mm: ss. ss AM | PM, and the date and time can be separated by a special character. the MDYAMPMw. d in forma [from the Internet (http://www.68idc.cn)] t reads datetime values with optional separators in the form mm-dd-yy Hh: mm: ss. ss AM | PM, and requires a space between the date and the time. The YMDDTTMw. d contains reads datetime values with required separators in the form Yy-mm-dd/hh: mm: ss. ss. Example

16mar2012/11:23 PM	1647559380.0

Writes SAS date values in the form Yymmdd or Yy-mm-dd, where a hyphen is the separator and the year appears as either 2 or 4 digits.

YYMMDDw. Argumentsw

Specifies the width of the output field.

Default	8
Range	2-10
Interaction	When w has a value of from 2 to 5, the date appears with as much of the year and the month as possible. when w is 7, the date appears as a two-digit year without hyphens.

DetailsThe YYMMDDw. format writes SAS date values in the form Yymmdd or Yy-mm-dd. Here is an explanation of the syntax: Yyis a two-digit or four-digit integer that represents the year. -is the separator. mmis an integer that represents the month. ddis an integer that represents the day of the month. comparisonsThe YYMMDDw. d format is similar to the YYMMDDxw. d format, cipher t the YYMMDDxw. d format contains separators, such as a colon, slash, or period between the year, month, and day. exampleThe following examples use the input value of 18720, which is the SAS date value that corresponds to limit L 3, 2011.
