There are a few different types of timing chips. Mats placed on the ground at the start and finish lines act as sensors for the timers. These chips do not begin timing until the runner has crossed the start line and stop timing the moment the finish line is crossed. In large races with thousands of participants, it may take runners at the back of the starting pack more than 20 minutes to cross the start line after the race officially begins. Runners receive a chip prior to the race that has been programmed with their own information. As a way to calculate each participant’s time more accurately, runners are given special electronic timing chips. This timing method is also known as net timing. Although certain race organisers choose to sound a horn instead of using a gun to start the race, the theory for this timing method remains the same. This can result in a much slower finishing time than what the runner actually ran. Even if it takes a runner several minutes to cross the start line during a major event such as a marathon, they are still being timed from the moment the gun is fired until they cross the finish line. At the beginning of most major races, a gun is fired into the air as a way to indicate the official commencement of the event.Ī timer is started immediately following the gunfire.
#Finishtime code#
And, any code you may have implemented to fix a timezone conversion error should now not be needed.Using a gun to start a race has been a longstanding tradition and was one of the only reliable methods for timing before the advent of modern technology. extend FldLabTransStartDateNP instead of FldLabTransStartDate). We can say that any classes which extend one of the original field validation classes should now extend the new field validation classes (i.e. The new field validation classes for STARTDATE, STARTTIME, FINISHDATE, and FINISHTIME are simply extensions of the old field validation classes, to implement the functionality described above.įor example, FldLabTransStartDateNP extends FldLabTransStartDate (which is still present amongst your class files).īecause neither database column names nor the names of the fields exposed in the UI were changed, we had hoped to avoid any upset to customer code. (This is where the timezone conversion problem is fixed: with both date and time values saved to the same column, we can perform the timezone calculation via the framework.) When both date and time values are populated, the DATETIME database column will be populated in addition to the DATE and TIME columns.
We also created two new persistent attributes, STARTDATETIME and FINISHDATETIME. To the best of our ability, to ensure as little disruption to clients as possible.Ģa - by not changing the UI attribute nameĢb - by not changing the existing database column name To enable time zone functionality when both the date and time are entered for the Start and/or Finish dateĢ. They write values to the same database columns which were written to before, STARTDATE, STARTTIME, FINISHDATE, FINISHTIMEġ. These classes behave as the old four attributes did when they were persistent. Each of the four database columns which used to be associated to these now non-persistent attributes is instead associated to one of four new persistent attributes, STARTDATEENTERED, STARTTIMEENTERED, FINISHDATEENTERED, FINISHTIMEENTERED. The four datetime attributes in Maximo 7.5, STARTDATE, STARTTIME, FINISHDATE, FINISHTIME, were changed to nonpersistent.
#Finishtime update#
The goal of the update was to resolve ongoing customer pain related to lack of time zone conversions of datetime values. These changes were made during a design update for the Maximo 7.6.0.0 release. Go to Database Configuration -> LABTRANS ->STARTDATE is persistent and the java class associated to this field is Go to Database Configuration -> LABTRANS ->STARTDATE is non-persistent and the java class associated to this field is .FldLabTransStartDateNP Also the java class associated to this field is different, it's changed to .FldLabTransStartDateNP however in 7.5 it was. LABTRANS.STARTDATE field is not persistent in 7.6.0.1. LABTRANS.STARTDATE is non-persistent in Maximo 7.6
