Auto-select backup set on restore when time target is specified.

Browse Source 
Auto-selection is performed only when --set is not specified. If a backup set for the given target time cannot not be found, the latest (default) backup set will be used.

Currently a limited number of date formats are recognized and timezone names are not allowed, only timezone offsets.
