Using custom date format - google-apps-script

Question

I have this working script to sent mails with data from a Google sheet:
function SendEmail() {
let timestamp = 0
let poid = 1
let sku = 2
let qty = 3
let description = 4
let licenseid = 5
let itcost = 6
let total = 7
let company = 8
let contact = 9
let contactmail = 10
let endusermail = 11
let address = 12
let country = 13
let status = 14
let suppliermail = 15
let currency = 16
let otherinfo = 17
let brand = 18
let comment = 19
let cc = 20
let emailTemp = HtmlService.createTemplateFromFile("MAIL")
let ws = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("DATA")
let sd = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("DATA2")
let data = ws.getRange("A2:V" + ws.getLastRow()).getValues()
let sData = sd.getRange("B2:J" + sd.getLastRow()).getValues()
let sInfo = sData.map(function (r) { return r[0] })
data = data.filter(function (r) { return r[14] == 'SENTNOW' })
if (data.length) {
let found = false
data.forEach(function (row) {
emailTemp.ts = row[timestamp].toLocaleString("da-DK")
emailTemp.po = row[poid]
emailTemp.co = row[contact]
emailTemp.cm = row[company]
emailTemp.ad = row[address]
emailTemp.cu = row[country]
emailTemp.cn = row[contactmail]
emailTemp.sk = row[sku]
emailTemp.de = row[description]
emailTemp.qt = row[qty]
emailTemp.it = (row[itcost]).toLocaleString("da-DK")
emailTemp.to = (row[total]).toLocaleString("da-DK")
emailTemp.ce = row[comment]
emailTemp.cy = row[currency]
emailTemp.eu = row[endusermail]
emailTemp.li = row[licenseid]
emailTemp.ot = row[otherinfo]
let indexSupp = sInfo.indexOf(row[15])
if (indexSupp > -1) {
//only change status if supplierdata email is found
found = true
emailTemp.spname = sData[indexSupp][1]
emailTemp.saddress1 = sData[indexSupp][2]
emailTemp.saddress2 = sData[indexSupp][3]
emailTemp.scountry = sData[indexSupp][4]
emailTemp.sterms = sData[indexSupp][5]
emailTemp.scurrency = sData[indexSupp][6]
emailTemp.sothers = sData[indexSupp][7]
emailTemp.vat = sData[indexSupp][8] * 100
emailTemp.totvat = (row[total] * sData[indexSupp][8]).toLocaleString("da-DK")
emailTemp.totandvat = (row[total] + (row[total] * sData[indexSupp][8])).toLocaleString("da-DK")
let subjectLine = "Subject line # " + row[poid]
let htmlMessage = emailTemp.evaluate().getContent()
//only send email if supplierdata email is found
try {
GmailApp.sendEmail(
row[suppliermail],
subjectLine,
"",
{ name: 'Name', htmlBody: htmlMessage, bcc: 'myemail#domain.com' })
}
catch (err) {
SpreadsheetApp.getUi().alert(err)
}
}
})
if (found) {
let sh = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("DATA")
.getRange('O2:O')
.createTextFinder('SENTNOW')
.replaceAllWith('SENT')
}
}
}
Only problem is the date format emailTemp.ts = row[timestamp].toLocaleString("da-DK")
This give output date-format "11.2.2022 06.00.00" within the e-mail sent to the reciever.
What I wish is the date to be just "02/11/2022"
I tried emailTemp.ts = row[timestamp].toLocaleString("da-DK").getDisplayValue() but that was not working.
Any suggestions ?

You're going to have to figure out your time zone but try this.
emailTemp.ts = Utilities.formatDate(row[timestamp],"GMT","dd/MM/yyyy");
Reference
Utilities.formatDate()
