unknown dateTime difference between typescript and java

Question

i am creating a project in angular and spring boot.

upon a certain event i send a date type object (called start time) from angular to spring boot which is written is in java i am facing 2 problems:

when i send the startTime from angular it is sent in indian standard time. but when i receive the start time in the back-end it is stored in utc format so there is -5.30 time difference
when i bring back the startTime at time of login (from back-end) i can display it in form of console.log(startTime) but when i do startTime.getHours(),startTime.getMinutes() etc. it shows an error that the getHours() is not a function of startTime

guys can anyone help me with both of the problem..

here is my scheduleData.ts which has startTime

export class scheduleData {
    public StartTime: Date;
    public EndTime: Date;
}

now here is my java code

public class ScheduleDataModel {

    public LocalDateTime StartTime;
    public LocalDateTime EndTime;

}

when you get it back from server, you need to parse it again to a date object. — whatamidoingwithmylife

You should follow the Java Naming Conventions: variabele names and method names should be written in camelCase. — MC Emperor

1.) If you send or receive a date, the informaton is sent as a date string. In most cases it's a part of a json. You must always send (or get) a timezone.

2.) You get a string. You have to parse it:

const d = new Date(yourDateString);
