_D

Converts millisecond timestamps or Date objects to time strings.

Time string. string

_D() _D(timestamp) _D(timestamp, fmt)

Millisecond timestamp or Date object. timestamp false number、object Format string, JavaScript language default format: yyyy-MM-dd hh:mm:ss; Python language default format: %Y-%m-%d %H:%M:%S; C++ language default format: %Y-%m-%d %H:%M:%S. fmt false string

function main(){
    var time = _D()
    Log(time)
}

def main():
    strTime = _D()
    Log(strTime)

void main() {
    auto strTime = _D();
    Log(strTime);
}

Get and print the current time string:

function main() {
    Log(_D(1574993606000))
}

def main():
    # Running this code on a server in Beijing time: 2019-11-29 10:13:26 , a docker on another server in another region results in: 2019-11-29 02:13:26
    Log(_D(1574993606))

void main() {
    Log(_D(1574993606000));
}

The timestamp is 1574993606000, using the code conversion:

function main() {
    Log(_D(1574993606000, "yyyy--MM--dd hh--mm--ss"))   // 2019--11--29 10--13--26
}

def main():
    # 1574993606 is timestamped in seconds.
    Log(_D(1574993606, "%Y--%m--%d %H--%M--%S"))        #  2019--11--29 10--13--26

void main() {
    Log(_D(1574993606000, "%Y--%m--%d %H--%M--%S"));    // 2019--11--29 10--13--26
}

Formatting with the parameter fmt is different for JavaScript, Python, and C++ languages, as shown in the following examples:

Returns the current time string without passing any parameters. When using the _D() function in the Python strategy, you need to be aware that the parameters passed are second-level timestamps (millisecond-level timestamps in the JavaScript and C++ strategies, where 1 second is equal to 1000 milliseconds). When using the _D() function to parse a time string with a readable timestamp in the live trading, you need to pay attention to the time zone and time setting of the operating system where the docker program is located. The _D() function parses a timestamp into a readable time string depending on the time of the docker’s system.
