Moment.js时区：在日期范围内的数组中查找项目时出现问题

Question

I have an array of programs. Each of which has start_date and end_date.

I want to find the current running program in the array by checking my current date in the range of each program's start_date and end_date.

The problem is that the programs were added in a specific time zone, but the dates don't have the time zone info on them.

I have tried setting offsets by the time zones that the program is created. But it didn't help.

const range = moment.range(moment(el.start_date), moment(el.end_date));

moment().within(range); This works well in the timezone that the program was created.

moment().utcOffset(240).within(range); I tried to fix the problem like this, but it didn't help.

Answer 1

If you happen to know the timezone that the programs start_date and end_date should have you can actually add the timezone to them! Moment-Timezone has examples here on how to add a timezone to a date.
