使用Java脚本仅将本地TimeZone更改为Default UTC

Question

I need to change the local or current TimeZone to Default UTC ( GMT+0000 ) time zone.

I used the predefined javascript function toLocaleString , but some machines has their own datetime format so the service request gets mismatched.

My requirement is just change the TimeZone without changing the current value ( NO CONVERSTION )

let dtime = new Date();
console.log(dtime);

Output: Fri Jul 07 2017 17:07:32 GMT+0530 (India Standard Time)

Required Format is Fri Jul 07 2017 17:07:32 GMT+0000 (???)

Scenario : I'm selecting DOB in DatePicker ( Angular Material ), Its returning the datetime offset value. If I pass those value from client to Server , it automatically converts it to Local to UTC Default.

For Example : I'm selecting DOB as 1990-01-01 in datepicker , it returns the value 1990-01-01 00:00:00 but in HTTP call it goes as 1989-12-31 18:30:00 . Because I'm in INDIA ( UTC +0530 ) , so it subtracts the 05 Hours and 30 Minutes. This is the issue I'm facing.

Kindly assist me.

You can try the following piece of code

date.setMinutes((date.getTimezoneOffset() * -1));

No need of localization, use this code just before doing any service call. It will pass you the exact date what you selected in the datepicker.

It will work in all timezone (+) and (-),

Example: 1990-01-01 00:00:00 GMT+0530 (India Standard Time) , the above said code covert it as 1990-01-01 05:30:00 GMT+0530 (India Standard Time) . While on Service it converts it as 1990-01-01 00:00:00 .

I think it will solve your problem.
