Daylight Saving Time date conversion

Currently in my system I use the following code, to convert the dates coming in ajax. new Date(parseInt(data.replace(/\/Date\((-?\d+)\)\//, '$1')))

Where the variable data is a string that comes in format '/Date(1508551200000)/', so you can replace the variable with this string to test.

Now my problem began to appear on this date, because when I convert it with the code above gives the following result:

Fri Oct 20 2017 23:00:00 GMT-0300 (Official Time in Brazil)

But the real value is 21/10/2017, when doing a survey find that this date was the beginning of Daylight Saving Time 2017 and with that it decreased by 1hr, so I found that the dates in Daylight Saving Time are having this same problem

How can I make this conversion to q it ignore this and return me the value q I wish, without decreasing in 1hr, in case ignoring this daylight saving time conversion.

Use the method toLocaleString() and then convert the result into Date object:

var data = '/Date(1508551200000)/';
data = new Date(parseInt(data.replace(/\/Date\((-?\d+)\)\//, '$1'))).toLocaleString('pt-BR', { timeZone: 'America/Sao_Paulo' });
var dt = data.substring(0, 10).split("/");
data = new Date(dt[2], dt[1] - 1, dt[0]);

console.log(data);

    It would not have as it gives me the result in the Date object, instead it is already formatted?

    Besides .toLocaleString(), gives way that was passed, because if the person access the system in another zone will display divergent information

  • I will see here... but in case, would add . toLocaleString("en")

    in the case only this would not be enough, would have to set Timezone tb, for example .toLocaleString('pt-BR', { timeZone: 'America/Sao_Paulo' });

  • That’s right. Look now.
