Variables

var (
	DB *gorm.DB
)

var Models = map[string]*ModelDescriptor{}

var NowFunc = func() time.Time {
	return time.Now()
}

NowFunc returns current time, this function is exported in order to be able to give the flexibility to the developer to customize it according to their needs, e.g:

gorm.NowFunc = func() time.Time {
  return time.Now().UTC()
}
