Hi Community,

We are using JavaScript on the form to calculate the next date and time based on a day of the week, hour and minute.

We are using the following function to calculate the next date.

> function getNextDate(startdate, nextDay, nextHour, nextMinute) {
> 
> &nbsp; &nbsp; var resultDate = new Date(startdate.getTime());
> 
> &nbsp; &nbsp; resultDate.setDate(startdate.getDate() + (7 + nextDay- startdate.getDay()) % 7);  
> &nbsp;&nbsp; &nbsp;resultDate.setHours(nextHour);  
> &nbsp;&nbsp; &nbsp;resultDate.setMinutes(nextMinute);  
> &nbsp;&nbsp; &nbsp;resultDate.setSeconds(0);  
> &nbsp;&nbsp; &nbsp;resultDate.setMilliseconds(0);  
> &nbsp;&nbsp; &nbsp;  
> &nbsp; &nbsp; return resultDate;  
> }

&nbsp;

The returned date is ok in GMT-4. How can we get the date calculated in GMT so that when it is saved in the BDM Date-Time (no time zone) it is impacted by the timezone.

Hi,

Did you have a look to [this thread](https://stackoverflow.com/questions/439630/create-a-date-with-a-set-timezone-without-using-a-string-representation/439871#439871) ?

I recommend using a `DATE-TIME (No Timezone)` type in your BDM to avoid dealing with this kind of timezone offsets issues (if it fits your use case ofc).

Using this type, you can post a ISO-8601 format string date like `2021-08-03T09:05:00` and ignore the timezone.

Hi Romain,

We are using the Date-Time (No Timezone). (question updated)

It looks like the timestamp is calculated properly&nbsp;but when the date is set using javascript&nbsp;in the UI designer, the widget does not trim the timezone.&nbsp;

What is the best way to get around this?
