What's New in SAS 9.4 Formats and Informats

Overview

New formats write date, time, and datetime values based on user local time.
Some format values might differ slightly when the DECIMALCONV= system option is set to STDIEEE.
For SAS 9.4, there are no new or enhanced informats.

New SAS Formats

The following formats are new:
B8601DXw.
Adjusts a Coordinated Universal Time (UTC) datetime value to the user local date and time. Then, writes the local date and time by using the ISO 8601 datetime and time zone basic notation yyyymmddThhmmss+hhmm.
B8601LXw.
Writes datetime values as local time by appending a time zone offset difference between the local time and UTC, using the ISO 8601 basic notation yyyymmddThhmmss+|-hhmm.
B8601TXw.
Adjusts a Coordinated Universal Time (UTC) value to the user local time. Then, writes the local time by using the ISO 8601 basic time notation hhmmss+|–hhmm.
E8601DXw.
Adjusts a Coordinated Universal Time (UTC) datetime value to the user local date and time. Then, writes the local date and time by using the ISO 8601 datetime and time zone extended notation yyyy-mm-ddThh:mm:ss+hh:mm.
E8601LXw.
Writes datetime values as local time by appending a time zone offset difference between the local time and UTC, using the ISO 8601 extended notation yyyy-mm-ddThh:mm:ss+|-hh:mm.
E8601TXw.
Adjusts a Coordinated Universal Time (UTC) value to the user local time. Then, writes the local time by using the ISO 8601 extended time notation hh:mm:ss+|–hh:mm.

Format Output Differences Due to the DECIMALCONV= System Option

When the DECIMALCONV= system option is set to STDIEEE, SAS converts and formats decimal values using the IEEE Standard for Floating-Point Arithmetic 754–2008. This standard improves the accuracy of floating point numbers. The output written for the following format might differ slightly from previous releases:
BESTDw.p E8601TZw.d S370FPDUw.d
B8601DTw.d HHMMw.d S370FZDw.d
B8601TMw.d HOURw.d S370FZDLw.d
COMMAw.d MDYAMPMw.d S370FZDSw.d
Dw.d MMSSw.d S370FZDTw.d
DATEAMPMw.d NEGPARENw.d S370FZDUw.d
DATETIMEw.d NUMXw.d TIMEw.d
DOLLARw.d PDw.d TIMEAMPM
DOLLARXw.d PERCENTw.d TOD
Ew. PERCENTNw.d w.d
E8601DTw.d PVALUEw.d ZDw.d
E8601TMw.d S370FPDw.d
