You can represent a dateTime element with the following physical
types:
- TimeSeconds. This
is a 4 byte integer that represents the number of seconds since the epoch.
- TimeMilliSeconds.
This is an 8 byte integer that represents the number of milliseconds since
the epoch.
These types provide a way for c time_t and Java dateTime representations
to be parsed.
The epoch (time 0) is specified by a format string. To change
the epoch you must update the physical properties of your dateTime element:
- In the Physical representation section you must set the Physical
Type to either Time Seconds or Time Milliseconds.
- In the Format field
set the value to the format of "yyyy-MM-dd'T'HH:mm
ZZZ". For example, 2000-01-01T12:59
+00:00.
