Translating PHP strtotime function into Javascript

I have a PHP function which calculates the time difference (hr/min/sec) of two values:
$mf_start_time = '10:00:00';
$mf_end_time = '11:00:00';
$st_start_time = '10:00:00';
$st_end_time = '12:00:00';
$sn_start_time = '10:00:00';
$sn_end_time = '13:00:00';
$ph_start_time = '10:00:00';
$ph_end_time = '14:00:00';
function time_interval($start,$end) {
$s = strtotime($start);
$e = strtotime($end);
if ($s < $e)
{
$a = $e - $s;
}
else
{
$e = strtotime('+1 day',$e);
$a = $e - $s;
}
$h = floor($a/3600);
$m = floor(($a%3600)/60);
$s = $a%60;
return trim(($h?$h.' hour ':'').($m?$m.' minute ':'').($s?$s.' second ':''));
}
$mf_duration = time_interval($mf_start_time,$mf_end_time);
$st_duration = time_interval($st_start_time,$st_end_time);
$sn_duration = time_interval($sn_start_time,$sn_end_time);
$ph_duration = time_interval($ph_start_time,$ph_end_time);
echo $mf_duration;
echo $st_duration;
echo $sn_duration;
echo $ph_duration;
My output for this is:
1 hour
2 hour
3 hour
4 hour
Now I am trying to translate this into Javascript, my problem is that I need to get strtotime() to work the same.
Here is what I tried in Javascript:
var mf_start_time = '10:00:00';
var mf_end_time = '11:00:00';
var st_start_time = '10:00:00';
var st_end_time = '12:00:00';
var sn_start_time = '10:00:00';
var sn_end_time = '13:00:00';
var ph_start_time = '10:00:00';
var ph_end_time = '14:00:00';
function time_interval(start,end)
{
var s = strtotime(start);
var e = strtotime(end);
if (s < e)
{
a = e - s;
}
else
{
var e = strtotime('+1 day',e);
var a = e - s;
}
var h = floor(a/3600);
var m = floor((a%3600)/60);
var s = a%60;
return trim((h?h+' hour ':'')+(m?m+' minute ':'')+(s?s+' second ':''));
}
var mf_duration = time_interval(mf_start_time,mf_end_time);
var st_duration = time_interval(st_start_time,st_end_time);
var sn_duration = time_interval(sn_start_time,sn_end_time);
var ph_duration = time_interval(ph_start_time,ph_end_time);
console.log(mf_duration);
console.log(st_duration);
console.log(sn_duration);
console.log(ph_duration);
This does not work because strtotime does not work for Javascript (error not defined). What can I use for that?

I did my best to replicate what your php does, however I don't know if this would be best practice in js, nor if it would be of the same use as you have in your php app. Hopefully this is a good starting point for you to see how js works 👍
var mf_start_time = '10:00:00';
var mf_end_time = '11:00:00';
var st_start_time = '10:00:00';
var st_end_time = '12:00:00';
var sn_start_time = '10:00:00';
var sn_end_time = '13:00:00';
var ph_start_time = '10:00:00';
var ph_end_time = '14:00:00';
function time_interval(start, end) {
var [sHour, sMinute, sSecond] = start.split(":");
var [eHour, eMinute, eSecond] = end.split(":");
var s = new Date();
s.setHours(sHour, sMinute, sSecond);
var e = new Date();
e.setHours(eHour, eMinute, eSecond);
var a;
if (s.getTime() < e.getTime()) {
a = e.getTime() - s.getTime();
} else {
e.setDate(e.getDate() + 1);
a = e.getTime() - s.getTime();
}
a = a / 1000;
var h = Math.floor(a/3600);
var m = Math.floor((a%3600)/60);
var s = a%60;
return (
(h ? h + ' hour ' : '') +
(m ? m +' minute ':'') +
(s ? s +' second ':'')
).trim();
}
var mf_duration = time_interval(mf_start_time, mf_end_time);
var st_duration = time_interval(st_start_time, st_end_time);
var sn_duration = time_interval(sn_start_time, sn_end_time);
var ph_duration = time_interval(ph_start_time, ph_end_time);
console.log(mf_duration);
console.log(st_duration);
console.log(sn_duration);
console.log(ph_duration);

One spreadsheet for each user

I have a code in GAS that works with a spreadsheet at the background and it works for a single use simultaneously.
The problem is that I want to create a copy of the spreadsheet, at the beginning of the code, for the interaction with every user that enter at the web App.
I tried two possibilities:
Create the duplicate at the beginning of the main.js in order to be recognized as global variable for every function in the code, but the code creates repetitive files when I interact with any element at the web page because Javascript read the codes with every interaction.
Create the duplicate within DoGet function creating at the end a variable linked to the Id or to the new file, but the rest of functions don't recognized that variable like a global variable, even declaring the variable at the beginning of the main.js
Code
var x;
if(x == null){
var myArray = crearnuevoarchivo(x);
x = myArray[0];
var database = myArray[1];

Global variables in Apps Script are different from global variables in other programming languages.
A way of storing global variables is making use of the PropertiesService class in Apps Script and using:
setProperty(key, value) - for storing the key-value pair;
getProperty(key) - for retrieving the value associated with the key.

Keep Weather info even when offline

So I'm creating a widget for the iPhone lockscreen using CSS/HTML. I can't figure out how to keep the weather info from disappearing when the phone screen turns off after a minute or when the phone is offline. Any tips? Here's the code:
<script type="text/javascript">

Adobe AIR readLine

I need to process a text file one line at a time. In BASIC, I could use a readline command, which would read until the next carriage return/line feed.
How would you write a function for looping through a file one line at a time in AIR?
var myDir = air.File.documentsDirectory;
var myFile = myDir.resolvePath("Test.txt");
if (myFile.exists) {
var myFileStream = new air.FileStream();
myFileStream.open(myFile, air.FileMode.READ);
var myByteArray = new air.ByteArray();
myFileStream.readBytes(myByteArray,0,myFileStream.bytesAvailable);
air.Introspector.Console.log(myByteArray.length);
} else {
alert ('File not found.');
}

var LineNumber;
var ItemCode;
var OrderCode;
var Qty;
var myDir = air.File.documentsDirectory;
var myFile = myDir.resolvePath("Test.txt");
if (myFile.exists) {
var myFileStream = new air.FileStream();
myFileStream.open(myFile, air.FileMode.READ);
var myData = new air.ByteArray();
myFileStream.readBytes(myData,0,myFileStream.bytesAvailable);
var str = myData.toString();
var Pos = 0;
var Tab = 0;
var CRLF = 0;
EOL = str.indexOf("\r",Pos);
while (EOL > 0) {
Tab = str.indexOf('\t',Pos);
LineNumber = str.substring(Pos,Tab);
Pos = Tab + 1;
Tab = str.indexOf('\t',Pos);
ItemCode = str.substring(Pos,Tab);
Pos = Tab + 1;
Tab = str.indexOf('\t',Pos);
OrderCode = str.substring(Pos,Tab);
Pos = Tab + 1;
CRLF = str.indexOf('\r',Pos);

}
} else {
