When you enter date and time using the DATE_AND_TIME data type (DT), your entries are stored in binary coded decimal format in 8 bytes. The DATE_AND_TIME data type has the following range:

• DT#1990-1-1-0:0:0.0 to DT#2089-12-31-23:59:59.999

The following examples show the syntax for the date and time for Thursday, December 25, 1993, at 8:12 and 34,567seconds in the morning. The following two formats are possible:

• DATE_AND_TIME#1993-12-25-8:12:34.567

• DT#1993-12-25-8:12:34.567

The following special IEC (International Electrotechnical Commission) standard functions are available for working with the DATE_AND_TIME data type:

• Convert date and time of day to the DATE_AND_TIME format

• FC3: D_TOD_DT

• Extract the date from the DATE_AND_TIME format

• FC6: DT_DATE

• Extract the day of the week from the DATE_AND_TIME format

• FC7: DT_DAY

• Extract the time of day from the DATE_AND_TIME format

• FC8: DT_TOD

The following table shows the contents of the bytes that contain the date and time information for the example Thursday, December 25, 1993, at 8:12 and 34,567 seconds in the morning.

The permitted range for the data type DATE_AND_TIME is:
