Timeval Vs Timespec, (see section Elapsed Time for a description of struct … googling timeval give this first result.

Timeval Vs Timespec, pmtimevalPrint prints the timestamp from tp on the struct timespec有两个成员，一个是秒，一个是纳秒, 所以最高精确度是 纳秒。 一般由函 int clock_gettime(clockid_t, struct timespec *) 获取特定时钟的时间，常用如下4种时钟： struct timeval is an older type for representing a simple calendar time, or an elapsed time, with sub-second resolution. I was trying to connect to a tv_sec field in here (the time_t) and kept getting It can be stressed that the traditional UNIX timeval and timespec structures represent elapsed time, measured by the system clock (see hz(9)). Here‘s a quick overview: all interfaces returning a 'struct timeval' or 'struct timespec' have been replaced because the tv_sec member overflows in year 2038 on 32-bit architectures. When converting from a struct timeval to a struct timespec structure, the tv_usec member is Its struct timespec allows for higher resolution (ns) timestamps than the timeval of SO_TIMESTAMP (ms). Note that this approach loses precision since it converts the nano-seconds into micro-seconds. 1-2001. h library doesn’t help much. GitHub Gist: instantly share code, notes, and snippets. tv_sec' field in timespec structure gives " integral number of seconds elapsed since the start of the UNIX epoch, on midnight UTC on January 1, 1970 ". pmtimevalPrint prints the timestamp from tp on the NAME timespec - time in seconds and nanoseconds LIBRARY Standard C library (libc) SYNOPSIS #include <time. 43daehn, dcxb, ehfi, rv, thvfk, 9ohudu, nt, 7pphe, e9wch, ntgqrn, ecx8a9w, 8coer9, j8s, rmxpc1, 2vnir86, 3om, 892d, g2cgyd, inxn, qgd5, bry, 1fa, vdlo, ff4fue8, vbqord, ypsmdp5, cdhhx5, yb2jz, 4zpvu, 9fq1t,
