Can't reproduce benchmark results

Seems like Go standard library was fixed since this library was introduced, so now time.Parse beats datetime.ParseAny:

package bench

import (
    "testing"
    "time"

    "github.com/araddon/dateparse"
    "github.com/stretchr/testify/require"
)

func TestDateEquivalence(t *testing.T) {
    format := "2006-01-02"
    input := "1988-11-20"

    out1, err := time.Parse(format, input)
    require.NotNil(t, out1)
    require.NoError(t, err)

    out2, err := dateparse.ParseAny(input)
    require.NotNil(t, out2)
    require.NoError(t, err)

    require.True(t, out1.Equal(out2))
}

func TestTimeEquivalence(t *testing.T) {
    format := "2006-01-02 15:04:05.999999"
    input := "1988-11-20 11:12:13.444444"

    out1, err := time.Parse(format, input)
    require.NotNil(t, out1)
    require.NoError(t, err)

    out2, err := dateparse.ParseAny(input)
    require.NotNil(t, out2)
    require.NoError(t, err)

    require.True(t, out1.Equal(out2))
}

func BenchmarkDateParseStdLib(b *testing.B) {
    format := "2006-01-02"
    input := "1988-11-20"
    for i := 0; i < b.N; i++ {
        out, err := time.Parse(format, input)
        require.NotNil(b, out)
        require.NoError(b, err)
    }
}

func BenchmarkDateParseAraddonDateparse(b *testing.B) {
    input := "1988-11-20"
    for i := 0; i < b.N; i++ {
        out, err := dateparse.ParseStrict(input)
        require.NotNil(b, out)
        require.NoError(b, err)
    }
}

func BenchmarkTimeParseStdLib(b *testing.B) {
    format := "2006-01-02 15:04:05.999999"
    input := "1988-11-20 11:12:13.444444"
    for i := 0; i < b.N; i++ {
        out, err := time.Parse(format, input)
        require.NotNil(b, out)
        require.NoError(b, err)
    }
}

func BenchmarkTimeParseAraddonTimeparse(b *testing.B) {
    input := "1988-11-20 11:12:13.444444"
    for i := 0; i < b.N; i++ {
        out, err := dateparse.ParseAny(input)
        require.NotNil(b, out)
        require.NoError(b, err)
    }
}
