The Benefits of Cycle Time Increased profitability When your organization puts an emphasis on Cycle Time to control the speed of deliverability, you reduce costs and increase profitability. Īny typographical or formatting errors that appear in this page are most likely to have been introduced during the conversion of the source files to man page format. Cycle Time is commonly defined as the actual amount of time that it takes to create a product or work a process. The original Standard can be obtained online at.

It is easy for an ESL learner to get expressions confused. The utime() function only allows setting file timestamps to the nearest second. Marketing time is defined as an opinion of the amount of time it might take to sell a real or personal property interest at the concluded market value during the period immediately after the effective date of an appraisal, according to The Dictionary of Real Estate Appraisal, 6th Ed. You mean it doesnt sound logical to keep up with time Since times refers to a particular period, it sure makes sense to say keep up with the times The expression keep up with generally means to make an effort to keep something from getting too far ahead of you. int utime(const char *, const struct utimbuf *)
The following shall be declared as a function and may also be defined as a macro. The header shall define the time_t type as described in. The times shall be measured in seconds since the Epoch. The header shall declare the utimbuf structure, which shall include the following members: time_t actime Access time.
Utime vs time manual#
The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux. At one time this was supposed to be the CPU time in cycles, but modern standards like POSIX require CLOCKSPERSEC to be 1000000, giving a maximum possible precision of 1 µs. clock () seems to return the sum of user and system time. This manual page is part of the POSIX Programmer's Manual. time () returns the wall-clock time from the OS, with precision in seconds.
Utime vs time code#
I can't really post the whole code here as it amounts to a few hundred lines but I could perhaps extract the relevant bits of code.Access and modification times structure Prolog This module implements a subset of the corresponding CPython module, as described below. It's driving me nuts as this a MicroPython port from an old C++ script for an Arduino to decode morse code which worked OK, and I thought it was an ideal project for the Pico.
I've tried putting a print() statement in the loop and I can see the old and new values ramping up but they are nearly always the same value hence the diff usually being zero. Have I misunderstood the documentation for ticks_ms() or ticks_diff() ? The result I get is usually zero, sometimes one and very occasionally 2. Similar to utime, if tvp is a null pointer then the access and. OK, maybe I'm being naive but I assumed that if I take the result of utime.ticks_ms() and then did the same again about 60mS later and passed both values into utime.ticks_diff(new, old) I'd get a result which would approximate to 60 (mS). The new file access time is specified by tvp 0, and the new modification time by tvp 1.
