You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: rules.go
    path of file: ./repos/olivia/language/date
    
    the code of the file until where you have to start completion: package date

import (
	"fmt"
	"regexp"
	"strconv"
	"strings"
	"time"

	"github.com/olivia-ai/olivia/util"
)

const day = time.Hour * 24

// RuleTranslations are the translations of the rules in different languages
var RuleTranslations = map[string]RuleTranslation{
	"en":
    
func RuleToday(locale, sentence string) (result time.Time) {
	todayRegex := regexp.MustCompile(RuleTranslations[locale].RuleToday)
	today := todayRegex.FindString(sentence)

	// Returns an empty date struct if no date has been found
	if today == "" {
		return time.Time{}
	}

	return time.Now()
}
