If the number of d-characters to be encoded is zero, the length of the dstring shall be zero.
NOTE: The length of a dstring includes the compression code byte(2.1.1) except for the
case of a zero length string. A zero length string shall be recorded by setting the entire
dstring field to all zeros.

For the following descriptions Type refers to the most significant 4 bits of this
field, and TimeZone refers to the least significant 12 bits of this field.
$ The time within the structure shall be interpreted as Local Time since Type
shall be equal to ONE for OSTA UDF compliant media.
? Type shall be set to ONE to indicate Local Time.
$ Shall be interpreted as specifying the time zone for the location when this
field was last modified. If this field contains -2047 then the time zone has
not been specified.
? For operating systems that support the concept of a time zone, the offset of
the time zone (in 1 minute increments), from Coordinated Universal Time,
shall be inserted in this field. Otherwise the time zone portion of this field
shall be set to -2047.
Note: Time zones West of Coordinated Universal Time have negative offsets.
For example, Eastern Standard Time is -300 minutes; Eastern Daylight
Time is -240 minutes.
