Updated File List - google-apps-script

Question

I am using a script to show me new files in google drive so people can see that a file has been updated. The script worked fine with one or two users using the system but after migrating a few more we started getting errors about exceeding maximum execution time. Currently the script deletes the current list and recreates it each and every hour
function listFilesInFolder() {
//try {
// If you want a tree of any sub folder
//var parent = DriveApp.getFoldersByName("FOLDER_NAME").next();
// If you want to search from the top (root) folder
var files = DriveApp.getFiles();
var ss = SpreadsheetApp.openById("1XbAaoNTiRXKSUAovY-QUvnc8V2q68g7Q3z4NIH_ioTc");
var sheet = ss.getSheetByName("Sheet1");
var file,folder,folders,folderTop,newFiles,lastUpdated,difference;
var j = 0;
var data = []
var parentFolders = []
var newDate = new Date();
while (files.hasNext()) {
file = files.next();
lastUpdated = file.getLastUpdated();
difference = newDate.getTime() - lastUpdated.getTime();
if ((difference/86400000) < 100) {
folders = file.getParents();
while (folders.hasNext()) {
folder = folders.next();
folders = folder.getParents();
parentFolders.push(folder.getName())
}
folderTop = parentFolders[parentFolders.length -2]
data.push (new Array());
data[j].push(file.getName());
data[j].push(file.getLastUpdated());
data[j].push("open_in_new");
data[j].push("https://drive.google.com/file/d/"+file.getId()+"/edit");
data[j].push("folder_open");
if (file.getParents().hasNext())
{
data[j].push("https://drive.google.com/drive/u/0/folders/" + file.getParents().next().getId());
}
else
{
data[j].push("https://drive.google.com/drive/");
}
data[j].push(folderTop+"#xxx.net");
j = j+1;
}
}
sheet.deleteRows(2, sheet.getMaxRows()-1)
sheet.deleteColumns(2, sheet.getMaxColumns()-1)
sheet.clear()
sheet.appendRow(["File Name","Date Updated","View File","File Link", "Open Folder","Folder Link", "Cell" ]);
sheet.appendRow(["","","HyperlinkType(D)-iconType","", "HyperlinkType(F)-iconType","", "Permissions-Hidden"] );
var destinationRange = sheet.getRange(3, 1,j , 7);
destinationRange.setValues(data);
}
// catch (e) {
// Logger.log(e.toString());
// }
// }
function getFilesFromFolder(parent,targetSheet,topLevelName) {
var files = parent.getFiles();
var data
var file
while (files.hasNext()) {
file =files.next()
data = [
file.getName(),
file.getDateCreated(),
file.getSize(),
file.getUrl(),
file.getDescription(),
file.getLastUpdated(),
file.getMimeType(),
topLevelName+"#xxx.net"
];
targetSheet.appendRow(data);
row.push([file.getId(),
file.getName(),
file.getDateCreated(),
file.getSize(),
file.getUrl(),
file.getDescription(),
file.getLastUpdated(),
file.getMimeType()
]);
}
}
function getChildFolders(parent,targetSheet,topLevelName) {
var childFolders = parent.getFolders();
while (childFolders.hasNext()) {
var childFolder = childFolders.next();
getFilesFromFolder(childFolder,targetSheet,topLevelName);
getChildFolders(childFolder,targetSheet,topLevelName);
}
// Recursive call for any sub-folders
}
Thank you.

Here's a script that uses DriveActivity API to monitor changes to Google Drive. The Qwikstart is here and I took that script and modified it.
I hardwired the timezone into the query filter so you'll need to address that and there's also the variable n and nl that I used to limit the number of calls so that I would hit quota limits during development.
It generates the html for the results and displays everything in a dialog.
Code.gs:
/**
* Lists activity for a Drive user.
*/
function listDriveActivity() {
const dt=new Date();
const dt0=new Date(dt.getFullYear(),dt.getMonth(),dt.getDate()-1);
const dt1=Utilities.formatDate(dt0, Session.getScriptTimeZone(),"yyyy-MM-dd");
const dt2=Utilities.formatDate(dt0, Session.getScriptTimeZone(), "HH:mm:ss")
const dt3=dt1+"T"+dt2+"-07:00";
const dt4=Utilities.formatDate(new Date(dt3), Session.getScriptTimeZone(), "E MM/dd/yyyy HH:mm:ss")
var html='Recent Activities ' + dt4 + ' ' + Session.getScriptTimeZone();
html+='<style>td,th{padding:2px;border:1px solid black;overflow-wrap: break-word;\} table{table-layout:fixed;width:100%;}</style>';
html+='<table>';
html+='<tbody>';
html+='<tr><th>Time</th><th>Actors</th><th>Actions</th><th>Targets</th></tr>';
var token="";
var n=0;
var nl=10;//I needed to reduce the number of calls to not exceed quota during development
do{
var request = {pageSize: 10,filter:Utilities.formatString('time>=\"%s\"',dt3)};
var response = DriveActivity.Activity.query(request);
var activities = response.activities;
if (activities && activities.length > 0) {
for (var i = 0; i < activities.length; i++) {
var activity = activities[i];
var time = getTimeInfo(activity);
var actions = getActionInfo(activity.actions);
var actors = activity.actors.map(getActorInfo);
var targets = getTargetInfo(activity.targets);
//html+=Utilities.formatString('<tr><td style="width:15%;">%s</td><td style="width:15%;">%s</td><td style="width:25%;">%s</td><td style="width:35%;">%s</td></tr>',time,truncated(actors),actions,targets);
html+=Utilities.formatString('<tr><td>%s</td><td>%s</td><td>%s</td><td>%s</td></tr>',time,actors,actions,targets);
Logger.log(JSON.stringify(activities[i]));
if(++n > nl)break;;
}
} else {
html+='<br />No Further Activity';
}
token=response.nextPageToken;
}while(token!='' && n<=nl);
html+='</tbody></table><br />n=' + n;
SpreadsheetApp.getUi().showModelessDialog(HtmlService.createHtmlOutput(html).setWidth(1200), "Drive Activity")
}
