timezone adjustments

i have a spread sheet that i need to do caluations with mutiple timezones and those time zones can and will change. master user will set master time/date/timezone and the frequently changing user will supply their time zone. how do i get the spreadsheet to grab the right cell/differental so the user will be given the right time to be availble?

ubuntu 15.04
libreoffice 4.4.2.2

I checked in the help file and help wiki and did not find anything related to timezone considerations.

I am afraid you need to enter timezone information manually and than adjust formulas depending on the timezone used.

I recommend to also have a look at the free guides, which you can download from http://www.libreoffice.org/get-help/documentation/
