How to set up 24h project with P-T resources in multi time zones?



What's the best way to set up calendars for a project with 24hour coverage
and part time resources across 4 time zones making up the 24 hours, sometimes
with or without overlap. I'd like to show local times of each of the
resources' location, but ensure the Gantt chart shows complete working
coverage over a 24 hour period.

Hi Leanne,

Welcome to this Microsoft Project newsgroup :)

You're asking too much! I would recommend you base all your calendars on
GMT as the aircraft operating industry does, and allow local management to
sort out the local times.

Hope this helps - please let us know how you get on :)

Hi Leanne,

You can get *part* of what you want, but not all. You can use the
24 hours calendar as the Project Calendar (Project > Project
Information). I suggest then creating additional calendars for each
of your four resource groups.

For example a project being managed on the East Coast (GMT - 5) of
the US with resources from London, England.(GMT): I'd create a
base calendar for those London resources that shows the working day
starting at 13:00 and ending at 21:00, allowing for the 5 hours
difference from my standpoint. Create each of the 4 base calendars
and then when you create your resources, assign the appropriate base
calendar to the resource. As you assign the resources to the tasks,
the schedule of the tasks will shift to reflect the working time
from each resource.

A resource viewing my file in England, will have to know the off-set
reflected in their calendar.

I hope this helps. Let us know how you get along.

In theory - this approach works and we would expect to look at the Gantt view drilled into the level of hours and see offset bars showing the working times. However, this is not happening. Anyone discover a workaround for this aside from manually setting the start time for other zone resources?
