Expression builder using Date/Time

I'm trying to create an expression in the Expression Automator to compare a date in {{E1.result}} with the current date and time. Specifically, I want to compare it to now in the Asia/Kolkata timezone and also add 1 day to the current time in that timezone.

However, I’m running into a few issues:

• I can't seem to specify the timezone Asia/Kolkata directly in the now() function.
• I'm also unsure of how to add a time interval (like +1) to now()
