How to add or subtract hours from GlideTime value (NOT GlideDateTime or GlideDate)?

[subhadeep1618]

I have a GlideTime (Time) type field in my table --- this is not GlideDateTime or GlideDate

Say for example, start_time

Now I want to add and subtract hours to the retrieved value (e.g. 5 hours)

That is, I want to do something like:

var actual_start_time = start_time + 5;

OR

var actual_start_time = start_time - 5;

Can someone please tell me, what is the most simplest way this can be done.

Oh sorry to hear that i couldn't help but happy that you figured out yourself. Cheers!

Thanks,

If you want to add or subtract hours from a GlideTime value without converting it to GlideDateTime or GlideDate, you can use GlideDuration to represent the time difference and then add or subtract that duration. Here's how you can do it:

// Assuming 'start_time' is your GlideTime field
var start_time = gs.timeAsGlideTime("08:30:00"); // Replace with your actual GlideTime value

// Create a GlideDuration representing 5 hours
var hoursToAdd = new GlideDuration(5 * 60 * 60 * 1000); // 5 hours in milliseconds

// Add the duration to the start_time
var actual_start_time = new GlideTime(start_time);
actual_start_time.add(hoursToAdd);

// Subtract the duration from the start_time
var actual_start_time_subtract = new GlideTime(start_time);
actual_start_time_subtract.subtract(hoursToAdd);

gs.info("Original Time: " + start_time);
gs.info("Time after adding 5 hours: " + actual_start_time.getByFormat('HH:mm:ss'));
gs.info("Time after subtracting 5 hours: " + actual_start_time_subtract.getByFormat('HH:mm:ss'));

For your example 

// Assuming 'start_time' is your GlideTime field
var start_time = gs.timeAsGlideTime("08:30:00"); // Replace with your actual GlideTime value

// Convert the GlideTime to seconds (since there are 3600 seconds in an hour)
var start_time_seconds = (start_time.getHourOfDay() * 3600) + (start_time.getMinute() * 60) + start_time.getSecond();

// Add 5 hours (5 * 3600 seconds)
var new_time_seconds = start_time_seconds + (5 * 3600);

// Handle cases where new_time_seconds exceeds a day (86400 seconds)
new_time_seconds = new_time_seconds % 86400;

// Convert the result back to a GlideTime
var actual_start_time = new GlideTime();
actual_start_time.setDisplayValue((new_time_seconds / 3600) + ":" + ((new_time_seconds % 3600) / 60));

gs.info("Original Time: " + start_time);
gs.info("Time after adding 5 hours: " + actual_start_time);
