Apologies for the delay in my reply.
The times for timesheets are actually timezone agnostic. KeyPay doesn’t care what timezone they are in. So, for example, if the employee’s shift started at 9am Sydney time on 30/11, you would pass through ‘2015-11-30T09:00’
If the employee’s shift started at 9am Western Australian time, you would still pass through ‘2015-11-30T09:00’
