Custom DatePicker Field value not displaying updated value

[Pooja Sathyaraj]

I am updating a datepicker field of the child issues of an epic according to the Epic custom field.

The value gets updated, but it does not display in the custom date field in the issue.

This is my code

def msaEndDateCheck =  getFieldByName("MSA End Date").getValue()  as Date

childIssue.getCustomFieldValue("MSA End Date").setDate(msaEndDateCheck.getDate())

        childIssue.getCustomFieldValue("MSA End Date").setMonth(msaEndDateCheck.getMonth())

        childIssue.getCustomFieldValue("MSA End Date").setYear(msaEndDateCheck.getYear())

        childIssue.getCustomFieldValue("MSA End Date").setHours(msaEndDateCheck.getHours())

        childIssue.getCustomFieldValue("MSA End Date").setMinutes(msaEndDateCheck.getMinutes())

        childIssue.getCustomFieldValue("MSA End Date").setSeconds(msaEndDateCheck.getSeconds())
