PutDate (MQCHAR8)

This is the date when the message was put, and is part of the origin context of the message. For more information about message context, see Overview for MQMD and Message context.

• YYYYMMDD

where the characters represent:

YYYY

year (four numeric digits)

MM

month of year (01 through 12)

DD

day of month (01 through 31)

Greenwich Mean Time (GMT) is used for the PutDate and PutTime fields, subject to the system clock being set accurately to GMT.

If the message was put as part of a unit of work, the date is that when the message was put, and not the date when the unit of work was committed.

For the MQPUT and MQPUT1 calls, this is an input/output field if MQPMO_SET_ALL_CONTEXT is specified in the PutMsgOpts parameter. The contents of the field are not checked by the queue manager, except that any information following a null character within the field is discarded. The queue manager converts the null character and any following characters to blanks. If MQPMO_SET_ALL_CONTEXT is not specified, this field is ignored on input and is an output-only field.

This is an output field for the MQGET call. The length of this field is given by MQ_PUT_DATE_LENGTH. The initial value of this field is the null string in C, and 8 blank characters in other programming languages.
