Synchro time issue

[akio622]

basicaly im doing a simple UI that can send you the price of an item and the last price recorder but the thing is, the date is way too old and i dont know if its a problem on my side or just that this lib synchronisation is too slow. *
Take a look at my code if you want :

import datetime
import BackpackTF
from customtkinter import *
from BackpackTF import *

api_key = Currency(apikey="661a53e819f57a398c071231")

screen = CTk()
screen.geometry("500x400")
screen.maxsize(500,400)
screen.minsize(500,400)

set_appearance_mode('dark')

Item_name = CTkEntry(master=screen, placeholder_text="Item name", corner_radius=15)
Item_name.place(relx=0.5, rely=0.4, anchor=CENTER)

quality_type = CTkEntry(master=screen, placeholder_text="Quality type", corner_radius=15)
quality_type.place(relx=0.5, rely=0.5, anchor=CENTER)

is_craftable = CTkEntry(master=screen, placeholder_text="Craftable ?", corner_radius=15)
is_craftable.place(relx=0.5, rely=0.6, anchor=CENTER)

craftability_state = 0

if is_craftable == "yes":
craftability_state == 1
elif is_craftable == "no":
craftability_state == 0

def button_event():
global price, item_name_value, quality_type_value, is_craftable_value
item_name_value = Item_name.get()
quality_type_value = quality_type.get()
is_craftable_value = is_craftable.get().lower()

craftability_state = 0

if is_craftable_value == "yes":
    craftability_state = 1
elif is_craftable_value == "no":
    craftability_state = 0

try:
    price = api_key.item_price(item=item_name_value, quality=quality_type_value, craftable=craftability_state)

    value = price['value']
    currency = price['currency']
    timestamp = price['timestamp']

    date_time = datetime.datetime.fromtimestamp(timestamp)

    output_label = CTkLabel(master=screen, text=f"The price of this item is : {value} {currency}")
    output_label.place(relx = 0.5, rely=0.8, anchor=CENTER)

    output_label2 = CTkLabel(master=screen, text=f"Price date time : {date_time}")
    output_label2.place(relx = 0.5, rely=0.85, anchor=CENTER)


except Exception as e:
    print(f"An error occurred: {e}")

btn = CTkButton(master=screen, text="Print result", command=button_event)
btn.place(relx=0.5, rely=0.7, anchor=CENTER)

screen.mainloop()

PS: Can someone of this project update the library documentation on https://pypi.org/project/BackpackTF/
