The main time package when timezone is UTC formats the date in RFC3339 like this:
2019-10-10T10:20:33Z
and for example for Tehran timezone formats like this:
2019-10-10T10:20:33+03:30

But your package for UTC acts as other timezones and formats as
1398-08-15T10:20:22+00:00

I think for consistency with main package you should format same as main time package

hey
first i wanna thank for your great repo.
second i have a question
is it possible to use ptime as type for sql database ?
i'm using gorm to connect database

type User struct {
	gorm.Model
	DeletedAt   gorm.DeletedAt `gorm:"uniqueIndex:national_id_deleted_at_idx;uniqueIndex:phone_number_deleted_at_idx"`
	FirstName   string         `gorm:"type:varchar(50);index;not null;"`
	LastName    string         `gorm:"type:varchar(50);index;not null;"`
	NationalID  string         `gorm:"type:varchar(10);index;not null;uniqueIndex:national_id_deleted_at_idx"`
	PhoneNumber uint           `gorm:"type:BIGINT(10)index;not null;uniqueIndex:phone_number_deleted_at_idx"`
	BirthDate   ptime.Time     `gorm:"index;not null;"`
	Gender      Gender         `gorm:"not null;default:'active'"`
	Status      Status         `gorm:"not null;"`
	Children    []Child        `gorm:"foreignKey:ParentID"`
}

when i try to do this and migrate database i get this error

[error] invalid field found for struct user.User's field BirthDate: define a valid foreign key for relations or implement the Valuer/Scanner interface      

While appreciating the project, AddDate() not works correctly. As a sample, today is 2023-06-11 OR 1402/03/21

By using this sample (the dates of the days of the future years):

func main() {
	pt := pTime.Now()
	utility.UFileDelete("dates.txt")
	for i := 0; i < 3650; i++ {
		pd := pt.AddDate(0, 0, i)
		utility.UFileAppend("dates.txt", strconv.Itoa(i)+" : "+pd.Format("yyyy/MM/dd  E  MMMMM  D/RD  w/rw")+"\n                                             "+pd.Time().String()+"\n", false)
	}
}

The output is (end of 1402):

Today + 286 -> 1402/12/28 2024-03-18

Today + 287 -> 1402/12/29 2024-03-19
Today + 288 -> 1402/12/29 2024-03-19
Today + 289 -> 1403/01/01 2024-03-20
Today + 290 -> 1403/01/01 2024-03-20

Today + 291 -> 1403/01/02 2024-03-21

But with updating the code as below by adding the days to standard time package:

func main() {
	t := 10 * 365
	now := time.Now()
	utility.UFileDelete("dates.txt")
	for i := 0; i < t; i++ {
		p := now.AddDate(0, 0, i)
		pt := pTime.Unix(p.Unix(), 0)
		utility.UFileAppend("dates.txt", strconv.Itoa(i)+" : "+pt.Format("yyyy/MM/dd  E  MMMMM  D/RD  w/rw")+"\n                                                  "+pt.Time().Format(time.UnixDate)+"\n", false)
	}
}

...
Today + 281 -> 1402/12/28 2024-03-18
Today + 282 -> 1402/12/29 2024-03-19
Today + 283 -> 1403/01/01 2024-03-20
Today + 284 -> 1403/01/02 2024-03-21
...
Today + 286 -> 1403/01/04 2024-03-23
Today + 287 -> 1403/01/05 2024-03-24
Today + 288 -> 1403/01/06 2024-03-25
Today + 289 -> 1403/01/07 2024-03-26
Today + 290 -> 1403/01/08 2024-03-27
...

The last day of 1403 is 1403-12-30 which is equal to the 2025-03-20. Try to convert 2025-03-20 to the Solar Hijri by passing a time.Time object with 2025-03-20 value to the ptime.New. The result will be 1404-01-01.

Hi there,

Thanks for sharing this amazing useful library.

How can I set my now date location to ptime.Iran():

pt := ptime.Now()
fmt.Println(pt.Location())

// output: Local

Can not calculate correctly Sub Days with AddDate function
example set the time to 1400-01-01
and use FirstWeekDay function to return
and you see return 1400-06-26 instead of 1400-06-27
I think the problem is with the time zone (+04:30 and +03:30)

Hi Navid

strconv.Itoa(t.nsec) string length rarely goes less than 6 and because of you trying to get a string with lenght 6 of it run time error happening, the problematic code is :

"{ms}", "." + strconv.Itoa(t.nsec)[:6],

and the error is :
panic: runtime error: slice bounds out of range [:6] with length 5

I fixed it in my fork by adding "0" charcter as needed to end of it's string.

Good Luck.

Thanks

The code will going to panic if the input value of ptime.New() is the zero value of time.Time
line 222: func (m Month) String() string {
return months[m-1]
}
cause when the time equals to "0001-01-01 00:01" the month array is going to have '-1' index and it is going to panic

Hey bro, may you contribute in this topic: https://discourse.gohugo.io/t/9403/

Note: Hugo is the fastest static site generator.

I think The FirstDayOfMonth() method must be returns the first day of month and reset the time to 00:00:00, but the method only reset the date and keeps original time

when you add months or years you won't get an expected result in Jalali calendar.

Hi,

May you take a look at this topic: https://discuss.gohugo.io/t/are-native-non-gregorian-calendars-supported/2963/6 and share your info there.

• Hugo is a written-Go static site generator.

Cheers

can't compare two different times

Missing two important method!

• no method for validating date!
• no method for parse string date!

thanks!
