Error description
Timestamp difference in WSAS and CICS An application has the following setup: . IHS => WSAS =MQ=> CICS (1) =MRO=> CICS (2) . An http request comes into IHS and the application on WSAS generates a message and puts a timestamp (obtained by date() in java.util.Date) into the message. The message will be passed into MQ and then passed to CICS (1). The message will then trigger a transaction in CICS (1) for message translation and then use an MRO link to send the message to CICS (2). . Please note that all the components are on the same LPAR. And the intermediate CICS will not alter any context of the message being sent from WAS. . It was found that the time obtained in WAS and CICS (2) region (both are running on the same z/OS LPAR) do not synchronize. This has caused messages to be dropped in the CICS (2) region. The CICS (2) region will drop the incoming messages when either one of the following conditions are met: 1) timestamp in CICS (2) > time obtained in WAS + 20 seconds 2) timestamp in WAS >= timestamp in CICS (2) . This means that the timestamp obtained in WSAS is before (or leads) the timestamp in CICS. . This APAR is being taken by CICS to further investigate the problem. It looks like the problem may be in the CICS ABSTIME calculation within DFHEIDTI. This problem will be investigated to determine the appropriate resolution. .

Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: The time returned from CICS ASKTIME is * * earlier than the time returned from * * WSAS. * **************************************************************** * RECOMMENDATION: * **************************************************************** An application compares the time from WSAS (Web Services Application Server) with the time from CICS ASKTIME (returned in EIBTIME copied from CSATODP), expecting the time from CICS ASKTIME not to be earlier. However, in some instances, the time from CICS ASKTIME can be a second earlier than the time from WSAS. The reason for this difference is that CICS ASKTIME converts the milliseconds to units of 1/300th seconds and in doing so loses accuracy. Additional keyword: CSAJYDP
Problem conclusion
DFHEIDTI and DFHEIIC have been changed to obtain accurate values of time and date from the TIME macro to be used in the calculation of EIBTIME and EIBDATE. ABSTIME has also been updated to stay consistent with the new date and time.
