Is `System.currentTimeMillis()` correct across multiple processes?

问题 We have a situation where a master process writes to a log. It then spawns multiple worker processes which write to their own logs. (I wanted the workers to log through the master, but there was resistance to this idea for some reason.) What I want to know is, can I trust that the timestamps that end up in the multiple files are consistent with each other? i.e., if I merge the log files into a single file sorting by instant, will the order of events be true? Across all possible operating

Run a macro exactly 5 minutes after a different macro ends

问题 The following code runs different macros at specific times but sometimes they run into each other and make for the whole process to be excruciating long. I was wondering how I could run the macros labeled "MASTER" exactly 5 minutes after the macro before it is done instead of just having them on scheduled times. Sub Workbook_Open() If Weekday(Date) >= 2 And Weekday(Date) < 7 Then Application.OnTime TimeValue("15:14:00"), "MarketClose3" Application.OnTime TimeValue("17:15:00"), "Saveit"

Convert 32 bit unix timestamp to std::string using std::chrono

久未见 提交于 2020-11-28 08:22:38
问题 I am trying to use std::chrono to make a std::string but running into issues. Here is the C(-ish) code I want to mimick: std::uint32_t time_date_stamp = 1484693089; char date[100]; struct tm *t = gmtime(reinterpret_cast<const time_t*>(&time_date_stamp)); strftime(date, sizeof(date), "%Y-%m-%d %I:%M:%S %p", t); My starting point is always this std::uint32_t , it is from a data format I do not control. Sorry I do not have any C++ as a starting point, I do not even know how to make a std::chrono
