Only for the @db.Date not @db.DateTime, Also Int suggestions don't work for storing time in my opinion, 00:00:01 would have to be converted to 000001 which becomes just 1, // type YYYY = `${DIGIT}${DIGIT}${DIGIT}${DIGIT}` // too many literal types inferred error, // const [yyyy, mm, dd] = date.split('-'), // return new Date(Date.UTC(parseInt(yyyy, 10), parseInt(mm, 10) - 1, parseInt(dd, 10))), // If you want to apply new Date(2022, 9, 19) as saved 2022-9-19 in your timezone by parse(new Date(2022, 9, 19) ), export function getTZDateFromUTC(dateField: Date) {, return new Date(dateField.getFullYear(), dateField.getMonth(), dateField.getDate(), dateField.getHours() + (dateField.getTimezoneOffset() / 60)), /* eslint-disable @typescript-eslint/no-var-requires */.
