How to implement output the current time

[amiaogo]

For example, the expression：time.Now().Format("2006-01-02 15:04:05")，Is it supported?

[s6816112]

    functions := map[string]govaluate.ExpressionFunction {
	"timeFormat": func(args ...interface{}) (interface{}, error) {
		return time.Now().Format("2006-01-02 15:04:05"), nil
	},
}
expString := "timeFormat()"
expression, _ := govaluate.NewEvaluableExpressionWithFunctions(expString, functions)

result, _ := expression.Evaluate(nil)
