e.g. 2021-03-25, PDT timezone
the date with an added offset of the current time "2021-03-25T07:00:00.000Z"
// suppose the timezone is PDT
const originalDateString: string = '2021-03-25';
const originalDate: Date = new Date(originalDateString);
// originalDate -> Wed Mar 24 2021 17:00:00 GMT-0700 (Pacific Daylight Time)
const deserializedDateString: string = deserializeDateValue(originalDateString);
const deserializedDate: Date = new Date(deserializedDateString);
// deserializedDate -> Thu Mar 25 2021 00:00:00 GMT-0700 (Pacific Daylight Time)
Given a string that represents a date object with no timezone offset, adds the offset based on the client's current timezone, and returns it as a string
