We run a FTP server (Solaris 9) which various organisations around our country (New Zealand) connect to (ie: we are all in the same time zone). It seems that some (or possibly all) of them see the files on the server with timestamps which are incorrect by 13 hours. When we look at the files, the timestamps look correct. When I log on, TZ is as follows:
$ echo $TZ
What are the likely causes/solutions of/for this difference?
