Relative Call Times Explained

How Call, Call-30 and Call+60 work, what the dropdown shows, and what moves when crew call changes.

6 min readUpdated September 2026

What Are Relative Call Times?

Every crew call is stored as minutes before or after the General Crew Call. Call-30 is 30 minutes before crew call. When the General Crew Call changes, every call moves with it.

Tip: A clock time you type, like 6:30 AM, is converted to an offset when it is saved. It moves with crew call too.

Relative Call Time Formats

A plain number after Call is minutes. Hours and minutes take a colon, the same way the dropdown writes them, so Call-90 and Call-1:30 mean the same thing.

TypeMeaningExample (7 AM Crew Call)
CallSame as General Crew Call7:00 AM
Call-1515 minutes before crew call6:45 AM
Call-3030 minutes before crew call6:30 AM
Call-601 hour before crew call6:00 AM
Call-90 or Call-1:301 hour 30 min before crew call5:30 AM
Call+3030 minutes after crew call7:30 AM
Call+601 hour after crew call8:00 AM
Call+2:002 hours after crew call9:00 AM
Tip: Past the hour, the dropdown shows hours and minutes: an hour and a half before reads Call-1:30 | 5:30 AM. Type it the same way and you get the same time. Call-130 without the colon is 130 minutes.

Typing a Clock Time

There is no fixed clock time for a crew call. A clock time you type becomes an offset, so if crew call moves an hour, that person moves an hour too.

EntryWhat happens when crew call moves
Call-30Moves with crew call
6:30 AMSaved as an offset, so it moves with crew call
TBD, N/C, O/CStays as typed
Tip: After changing crew call, check anyone whose time had to stay put, such as a hard-out or a fixed pickup, and set them again.

Department-Level Relative Calls

Set a call in a department header on the CS Back and it is written to everyone in that department:

  • Hair/Makeup: Call-30
  • Locations: Call-60
  • Catering: Call-90
  • Change any one person on their own row afterwards

How G-Casper Pro Displays Times

The call sheet shows and prints the clock time. The offset only appears in the dropdown while you pick.

Changing General Crew Call

Change the GENERAL CREW CALL on the CS Front and it saves straight away. There is no preview. Every crew call moves with it, and so do Breakfast, Shooting Call and Lunch.
