fake time doesn't work as expected

[B4Dmonkey]

Hi, I'm testing this library out for use, I tried generating some time test data using the example in the read me but run into parse errors

This is my example struct

type Record struct {
	ID           int64
	RecordID     string    `csv:"API_ID" fake:"{number:100000,999999}"`
	Source       string    `csv:"source" fake:"{firstname}"`
	PurchaseDate time.Time `fake:"{year}-{month}-{day}" format:"2006-01-02"`
	RecordType   string	
	CreatedAt    time.Time `fake:"{year}-{month}-{day}" format:"2006-01-02"`
}

this is how I call it

var foo Record
err := gofakeit.Struct(&foo)

and this is what im seeing in my logs

2025/03/27 16:44:13 error generating foo data 0
parsing time "1912-8-13" as "2006-01-02": cannot parse "8-13" as "01"
2025/03/27 16:44:13 error generating foo data 1
parsing time "1955-9-8" as "2006-01-02": cannot parse "9-8" as "01"

I'll try and dig into the code to see if I can figure out what's going on but just wanted to raise this as I didn't see it as a pending issue

looks like golangs time parser wants 2 digits for month and day

I didn't get far but from what I can tell changing the formatting tags helped a bit but there were still errors.

I fell back to using functions to generate the data and will try and do a deeper dive once I have more time.

I havent tried it, nor do i have tests for it. but you might be able to use just {date}. then you wont need a format. but if you need the time part to just be 00:00:00 then {date} wont work.

If you figure something out, add some tests and submit a pr and ill get that in for you asap

thanks {date} works, once I free up some time ill try and add some test and update the readme to reflect this example
CreatedAt time.Time fake:"{date}"`

That would be a nice addition to the package.
