A warning should be noted to anyone using GMT or UTC offset's from here, in that the labels for them are actually misleading. If you are 4 hours before (West) of GMT, then you should be using GMT+4. This is because the value you are seeing is the POSIX offset, not the common name for the timezone. User beware.
