Yes. Technically that is a date field followed by a time field.  One aspect of 
ISO8601 that gets a bit unwieldy is that a space is not permitted. In a 
combined date/time field, the separator "T" must be used without space.  It 
will be about 3:45 PM EDT by the time I finish this note.

Properly that is 2009-03-12T15:45 is I wish to designate local time, or 
2009-03-12T15:45-04:00 if I wish to designate my time zone (relative to UTC).  
It is a bit lengthy for human readability, but ISO 8601 is really for machine 
parsing.  The spaces that would improve human readability are non compliant 
(although many choose to non-comply).

"Z" (Zulu) is reserved for UTC time zone, so above could be written 
2009-03-12T19:45Z.
