bitmex, Nonce is not increasing

Been trying to use the python api. Some works nicely, but bitmex authenticated api seems to have an issue with the nonce generation.

bitmex = ccxt.bitmex({
        "apiKey": BITMEX_API_KEY,
        "secret": BITMEX_API_SECRET
    })
balance = bitmex.privateGetUserWalletHistory()

This is the error:

ExchangeNotAvailable: bitmex GET https://www.bitmex.com/api/v1/user/walletHistory 400 Bad Request (possible reasons: invalid API keys, bad or old nonce, exchange is down or offline, on maintenance, DDoS protection, rate-limiting, {“error”:{“message”:“Nonce is not increasing. This nonce: 1503497932, last nonce: 1502567277932”,“name”:“HTTPError”}})

Missed the doc on overriding, thanks!

    # Python
    import ccxt
    import time
    bitmex = ccxt.bitmex({
        "apiKey": BITMEX_API_KEY,
        "secret": BITMEX_API_SECRET,
        "nonce": lambda: time.time() * 1000, #  ← milliseconds nonce
    })
    balance = bitmex.privateGetUserWalletHistory()

    // JavaScript
    let bitmex = new ccxt.bitmex({
        "apiKey": BITMEX_API_KEY,
        "secret": BITMEX_API_SECRET,
        "nonce": Date.now, // ← milliseconds nonce
    })
    balance = bitmex.privateGetUserWalletHistory()
