I wrote a silly elisp function that does the conversion for me.  Hah,
yeah ! exactly, I use it for the exact same thing, scheduling an interview
with someone on the other side of the planet.

So for example they ask me 

"Can you provide us with times when you're available for an interview ?"
and I just make a table and let them decide when:

    | time Tokyo         | time Sofia             |

    #+TBLFM: $1='(concat "<" (org-tz-conv $2 "Asia/Tokyo" "to") ">")

You said above you're using iCal (do you mean, Google Calendar or
Apple Calendar?). I'd be interested in setting this up as well, which one
should I be using ?

At this point in time I'm using Org-Mode's agenda to view events.
Should I try to sync them up with my phone and if so what is the recommended
way to go ?

This is the implementation of org-tz-conv:

    (defun org-tz-conv (stamp tz way)
      (let* (
             (current-tz-offset (shell-command-to-string "date +%z"))
             (stamp1    (concat (replace-regexp-in-string "[<>]" "" stamp) " " current-tz-offset))
             (date-cmd-p0  "TZ=%s date -d \"%s\"")
             (date-cmd-p1  "date --date=\"TZ=\\\"%s\\\" %s\"")
             (date-cmd-p2  " +\"%F %H:%M\"")
             (date-cmd-rendered1  (format date-cmd-p1 tz stamp1 ))
             (date-cmd-from  (concat date-cmd-rendered1 date-cmd-p2))
             (date-cmd-to    (concat (format date-cmd-p0 tz stamp1) date-cmd-p2))
             (shell-result-from (shell-command-to-string date-cmd-from ))
             (shell-result-to   (shell-command-to-string date-cmd-to   ))

             (result-from (replace-regexp-in-string "\n" "" shell-result-from) )
             (result-to   (replace-regexp-in-string "\n" "" shell-result-to  ) )
        (message shell-result-from)
        (message shell-result-to)
        (cond ((string-equal way "from") result-from)
              ((string-equal way "to"  ) result-to  ))
