date

问题 My friends and I are developing an app in android studio using Kotlin. We are quite new in app development but we have decent prior programming skills. For one of our functionalities we need to get current date and time. We tried all kinds of imports and methods, but none seem to work with SDK lower than 26. With our app we target devices with minimum API 19. For example: package hr.com.wap.wap import android.support.v7.app.AppCompatActivity import android.os.Bundle import kotlinx.android

问题 My configuration is Lisbon time zone. When I do new Date() I get my current local date/time which is Fri Apr 28 2017 01:10:55 GMT+0100 (GMT Daylight Time) When I get the ISO string with toISOString() it will apply the time zone and I will get: 2017-04-28T00:10:55.964Z The problem is that some minutes ago the date time was like this (yesterday): 2017-04-27T23:45:05.654Z I tried moment.js (new to this) and I did something like this document.write(moment('2017-04-28').format()) But I get this

问题 The following script calculates me next Friday and next Sunday date. The problem : the use of .toISOString uses UTC time. I need to change with something that outputs local time. I'm very new to javascript so I can't find the right property to use instead of .toIsostring.
