Setting a large number will complete the process faster, but may place a load on the server.<br>If not set or if 0 is set, the default value of 1000 will be used.| *1 The processing start time is described as a string array. In 24-hour format (HH:mm). The processing will be executed every day at the specified time. By describing multiple times, it is possible to execute multiple times in a day. The described time will be treated as the time zone specified by TimeZoneDefault in "[Service.json](/en/manual/service-json)". If another process is running at the specified time, it will be executed after that process finishes. If the same hour and minute are specified, the order in which the processes will start is undefined. *2 This has been discontinued from Pleasanter 1.4.7.0 and later versions. Processing will no longer be interrupted even if consecutive exceptions occur in the reminder function. ## Supported Versions |Supported versions|Body| |:--|:--| |1.3.7.0 and later|Added ReminderIgnoreConsecutiveExceptionCount<br>Added Reminder| |1.3.19.0 and later|Added SyncByLdapTime<br>Added SyncByLdap| |1.3.23.0 and later|Added DeleteSysLogsTime<br>Added DeleteSysLogs| |1.3.24.0 and later|Added DeleteTemporaryFilesTime<br>Added DeleteTemporaryFiles| |1.3.25.0 and later|Added DeleteTrashBoxRetentionPeriod<br>Added DeleteTrashBox<br>Added DeleteTrashBoxTime| |1.3.26.0 and later|Added EnvironmentVariables| |1.4.7.0 and later|Added ReminderIgnoreConsecutiveExceptionCount| |1.5.0.0 and later|Added DeleteUnusedRecord<br>Added DeleteUnusedRecordTime<br>Added DeleteUnusedRecordChunkSize|
