POAdding hours and minutes to a date with javascript
text
Body
copied!<p>I am building a meeting calendar based on time zones around the world. My problem is how to add or subtract the time zone from the user selected date in Javascript.</p> <p>For example, on the select form, the user will select the date from a form: I would then get the results and convert to a date as below...</p> <pre><code>var ldSelectDate = new Date(document.form1.year.value, document.form1.month.value, document.form1.day.value); </code></pre> <p>I would like to add 12 midnight to this object.</p> <p>I then read in an XML that gets the time zone difference in a string between two cities: such as "+0430" for Kabul or "-0400" for New York (on daylight savings time). This is based on GMT,.</p> <p>I then calculate the time zone difference between the two cities: which will return the string of "830". (I assume I have to return this as a date object?). I got this part done returning a string. I'm working with strings.</p> <p>I then want to loop through the 24 hours of the day, set Kabul at 12 midnight and then loop through. I can most likely figure this out - that is, set the date with the whole hours as I loop.</p> <p>My problem is painlessly subtract the "830" from Kabul to see what the meeting time will be in New York.</p> <p>It will be ideal if I can just subtract the hours and the minutes from the Kabul time. I noticed on here someone subtracting the hours in javascript, but not the minutes. BTW, that post didn't work for me.</p> <p>I did this with strings without the minutes, but I mess up with the minutes. There has to be an easier way.</p> <p>I would take a solution in either native Javascript or jQuery.</p> <p>Again, I need to subtract/add the time zone difference in hours and minutes to a certain date.</p> <p>Thanks</p>
