Abstract
A recording apparatus contains a timer that measures the current time based on a time zone. When writing a VOB onto a DVD, the recording apparatus refers to TM_ZONE recorded on the DVD, and judges whether the time zone which the timer is based on matches the time zone that the TM_ZONE specifies. If the two time zones do not match, the recording apparatus operates as follows. First, the recording apparatus obtains VOB_REC_TM that indicates the recording date/time of the VOB based on TM_ZONE. The recording apparatus then writes the VOB onto the DVD together with VOBI that is information of the VOB and contains (a) the obtained VOB_REC_TM; (b) LOCAL_TZ_TY indicating that the two time zones do not match and (c) LOCAL_TZ specifying the time zone which the timer is based on.
