Scriptrunner convert date time in data center to milliseconds

[Carla Ann Rowland]

Newbie to Scriptrunner and Scripting and Java. Working on video tutorial that calculates new date and time based on custom field:

it starts out and term of contract is date and time and adds 30 or 60 or 90 days to due date and assigns it to due date.  

I was typing this into ScriptRunner console and then TimeinMillis() was depreciated-- I need help to use new method.

// this script takes final payment date and calculates expiration date 364 days in future
//adaptation of youtube video

//GET value of Valid Period custom field (30, 60, 90 days)
//GET Build logic around what data is due date
//CALCULATION of due date
//INPUT of the due date

//issue type contract--workflow post function
// uses custom fields: Contract Warranty Expiration=10400, a date field,
// custom field valid period-- date field =10402
// and Invoice Final Payment Date=10401

//Get Managers
import com.atlassian.jira.component.ComponentAccessor //library call
import com.atlassian.jira.issue.MutableIssue
import java.util.*

def VALIDPERIOD = 10402 as Long //define custom field static field id in my instance

def datetoset

def customFieldManager=ComponentAccessor.getCustomFieldManager()
//get current issue in my instance
def issue = ComponentAccessor.getIssueManager().getIssueByCurrentKey("SP-24")
// GET custom field
def validPeriodCustomField = customFieldManager.getCustomFieldObject(VALIDPERIOD)
// get value
def validPeriodValue = issue.getCustomFieldValue(validPeriodCustomField)
// log.warn tells me what value it is pulling
log.warn("This is check getting valid period from issue:" + validPeriodValue)
// LOGIC around new contract due date --date to set
if (validPeriodValue=='30') {
datetoset = 30
}
else if (validPeriodValue == '60'){
datetoset = 60
}
else {
datetoset = 90
}
log.warn('date to set:'+ datetoset + ' line 41')
//set the value on issue using JAVA API

Calendar myDueDate = Calendar.getInstance()
myDueDate.add(Calendar.DATE, datetoset) //set new value
//get timestamp in java so JIRA can read it
//Timestamp dueDateTimestamp = new Timestamp(myDueDate.getTimeinMillis())

//from this point is where I get lost.

calendar.getTimeinMills()

issue.setDueDate(dueDateTimestamp)

log.warn('new due date is: ' + dueDateTimestamp)
log.warn ('issue due date is ' )

Hi @Carla Ann Rowland 

Please try the code below.

Calendar myDueDate = Calendar.getInstance();
myDueDate.add(Calendar.DATE, datetoset);
Timestamp dueDateTimestamp = new Timestamp(myDueDate.getTime().getTime())
