SFDT$–System Standard Format Date and Time
Recommended Date and Time Formats
Since there are many possible date and time format combinations, the following formats
are recommended as standard:
YYMMDD HHMM:SS format (1,2) –most compact
CCYY-MM-DD HHMM:SS format (4,2)
CCYY mmm ddd HHMM:SS format (8,2) –most descriptive
The element SFDTBL$ contains the ASCII character abbreviations for months and days.
It is accessed by external label SFDTBL$. These abbreviations may be changed to other
abbreviations for months and days, for example, when using languages other than
English.
SFDT$ can be called from both MASM and PLUS routines. It is available as a relocatable
element in the SYSLIB file (SYS$LIB$*SYSLIB) or SYS$*RLIB$ and in the SYSLIB
common bank SYSLIB$1. The relocatable and common bank entry points to SFDT$ are
listed in Appendix E.
22.1. MASM Interface
SFDT$ can be called directly from MASM programs. The packet for SFDT$ is described
in 22.1.1. The calling sequence for SFDT$ is described in 22.1.2.
22.1.1. Packet
The calling program must provide a five-word packet for SFDT$. The following MASM
PROC generates this packet:
label S$FDTPKT datefmt,timefmt,buflen,bufaddr[,sep][,offset]
The packet is shown in Figure 22–1.
0 tscell datefmt timefmt sep reserved version
01 offset numchar buflen errcode
02 bufaddr
03 date
04 time
