MDPT (8-byte character string)

Time when message was put.

This is part of the origin context of the message. For more information about message context, see Overview; also see the WebSphere MQ Application Programming Guide.

The format used for the time when this field is generated by the queue manager is:

• HHMMSSTH

where the characters represent (in order):

HH

hours (00 through 23)

MM

minutes (00 through 59)

SS

seconds (00 through 59; see note below)

T

tenths of a second (0 through 9)

H

hundredths of a second (0 through 9)

Note:

If the system clock is synchronized to a very accurate time standard, it is possible on rare occasions for 60 or 61 to be returned for the seconds in MDPT. This happens when leap seconds are inserted into the global time standard.

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

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

For the MQPUT and MQPUT1 calls, this is an input/output field if PMSETA is specified in the PMO 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 null character and any following characters are converted to blanks by the queue manager. If PMSETA is not specified, this field is ignored on input and is an output-only field.

After the successful completion of an MQPUT or MQPUT1 call, this field contains the MDPT that was transmitted with the message. If the message has no context, the field is entirely blank.

This is an output field for the MQGET call. The length of this field is given by LNPTIM. The initial value of this field is 8 blank characters.
