Note that there are a structural and syntactical problems in your  
example:

It should be

foo:myShop a gr:LocationOfSalesOrServiceProvisioning ;
	gr:hasOpeningHoursSpecification [
		a gr:OpeningHoursSpecification ;
		gr:opens "00:00:00"^^xsd:time ;
		gr:closes "23:59:59"^^xsd:time ] .

- gr:opens and gr:closes instead of open and close
- gr:hasOpeningHoursSpecification instead of g:openingHoursSpecification
- missing type for the blank node (can be inferred of course)

It's as Daniel says: The best way to indicate all-day opening hours is  
00:00:00 - 23:59:59. However, as per xsd:time, you must include the  
seconds:

foo:Mondays a gr:OpeningHoursSpecification ;
	gr:opens "00:00:00"^^xsd:time ;
	gr:closes "23:59:59"^^xsd:time .

If no time-zone suffix is included, the time is given in the local  
time valid at the location.
For a time in GMT/UTC, simply add a "Z" following the times:

foo:Mondays a gr:OpeningHoursSpecification ;
	gr:opens "00:00:00Z"^^xsd:time ;
	gr:closes "23:59:59Z"^^xsd:time .

Alternatively, you can specify an offset from the UTC time by adding a  
positive or negative time following the time:


foo:Mondays a gr:OpeningHoursSpecification ;

	gr:opens "00:00:00-09:00"^^xsd:time ;
	gr:closes "23:59:59-09:00"^^xsd:time .

or

foo:Mondays a gr:OpeningHoursSpecification ;
	gr:opens "00:00:00+09:00"^^xsd:time ;
	gr:closes "23:59:59+09:00"^^xsd:time .

Best
