unix-timestamp

问题 Ok so I want to check if my users are online or not, I think a good way of doing this is using the sessions table that laravel provides. I'm a newbie though so can anybody first of all explain to me what this data means. CREATE TABLE sessions ( id VARCHAR(40) NOT NULL, last_activity INT(10) NOT NULL, data TEXT NOT NULL, PRIMARY KEY ( id ) ); last_activity is a unix timestamp, that one is clear to me. My id = lGBzJ0dIWiebrwjFlkQAE19NHuNHvsPRVS7e4CRO This is equal to the cookie value but that

问题 I'm trying to find better way to convert DateTime to unix timestamp in C# I find out that there is a DateTimeOffset.ToUnixTimeMilliseconds method: public long ToUnixTimeMilliseconds() { return this.UtcDateTime.Ticks / 10000L - 62135596800000L; } What this method means? What the constants are used? UPD: I guess 10000L is converting from FRAME to Milliseconds. But what about 62135596800000L? 回答1: To explain this method: public long ToUnixTimeMilliseconds() { return this.UtcDateTime.Ticks /

问题 I have a function that I wrote (if there is a good standard substitute, please let me know...) time_t get_unix_time(string time_str) { time_t loctime; time(&loctime); struct tm *given_time; time_str = time_str.substr(0, time_str.find_first_of('.')); replace(time_str.begin(), time_str.end(), ':', ','); replace(time_str.begin(), time_str.end(), '-', ','); replace(time_str.begin(), time_str.end(), '/', ','); replace(time_str.begin(), time_str.end(), ' ', ','); given_time = localtime(&loctime);

问题 i'd like to make the DateTimefield of models accept unix timestamp (in seconds) values. I found this but the acepted solution doesn't work? unixtimestamp input in DataTimeField i.e. i don't see how adding '%s' as an input format will work, especially when the code for to_python() of the standard datetime field doesn't include any logic for handling unix timestamps. If there is a setting that allows me to do this great. Otherwise, what I think i want is to subclass DateTimeField and somehow

问题 In my javascript, I have a unix timestamp (in this instance `1318305600000") and I need to convert that into a human readable date via Javascript. How do I go about doing this? 回答1: var date = new Date(unix_timestamp*1000); var hours = date.getHours(); var minutes = date.getMinutes(); var seconds = date.getSeconds(); // will display time in 21:00:00 format var formattedTime = hours + ':' + minutes + ':' + seconds; For complete reference getDate() Returns the day of the month (from 1-31)

问题 I created DB from google chrome's Cookies file and one of the columns in the cookies table is expires_utc . The format of the column is like - 13169399213145330, which is more like unix time. But when i'm trying to use unix time converter, it gives wrong values. So, what format is that and how i can convert it to actually unix time? 回答1: So, after long researches on this topic, here is the solution: Chrome's cookies timestap's epoch starts 1601-01-01T00:00:00Z (Why? Because.) So, it's

问题 I have a fractional epoch timestamp, represented as double , that I would like to convert to an appropriate std::chrono::time_point . The epoch is the usual UNIX epoch since 1/1/1970. I know that there exists std::chrono::system_clock::from_time_t , but a time_t does not have a fractional part. What would be the best way to do this with C++11 means? This question is related to unix timestamp to boost::posix_time::ptime, except that it's asking for the C++11 rather than Boost version of it.
