Team,

We recently designed API to integrate Taleo and HCM but we are struck at the time zones, here is the issue:

We have offices in India, Germany, and US (EST and CST), when trying to run the employee load from HCM to Taleo it is picking up all the needed fields correctly but by default it's taking EST (heard it only its one time zone) for all the employees. Employees in India, Germany and CST are getting effected.
