Naive datetime timestamp(local time treated as UTC) in Python and Javascript

asUTCTimestamp.js

// convert a date to timestamp as if it is a UTC date
// in other words used to remove local timezone info and fake everything as UTC
// must beware the funky api naming

// workaround js UTC date things
// the general rule is treat date as naive datetime with no timezone info
// using UTC timezone is better since it won't change based on user's computer location
function asUTCTimestamp(date) {
    return Date.UTC(date.getFullYear(), date.getMonth(), date.getDate(),
        date.getHours(), date.getMinutes(), date.getSeconds(), date.getMilliseconds());
}

function asUTCDate(ts) {
    // not sure how this can work really
    var date = new Date(ts);
    return new Date(date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate(),
        date.getUTCHours(), date.getUTCMinutes(), date.getUTCSeconds(), date.getUTCMilliseconds());
