Fernando, Your GPS is probably as good as it gets as far as time accuracy is concerned. However your unit must be tracking or have been locked on recently. The internal clock does not have very good long term accuracy by itself. Actual time from the gps is accurate in the microsecond level. We use gps recievers to syncronize computer networks.
