SQL Count distinct times with a 30 minute difference

I'm trying to find a SQL query that will count the number of distinct start times that are at least 30 minutes different. I have a number of employees that are paid a credit when they start work on at least three distinct times in a week, where the start time is at least 30 minutes different from the other start times. For example: se...

Local time with milliseconds

Hello, how can I get current time with library boost. I can do this: ptime now = boost::posix_timesecond_clock::local_time(); tm d_tm = to_tm(now); But the last time unit of tm structure is second and I need in millisecond. Can I get current time with milliseconds? ...

Serious overhead in Python cProfile?

Hi expert Pythonists out there, I am starting to use cProfile so as to have a more detailed timing information on my program. However, it's quite disturbing to me that there's a significant overhead. Any idea why cProfile reported 7 seconds while time module only reported 2 seconds in the code below? # a simple function def f(a, b): c...

Why is gmtime implemented this way?

I happened across the source for Minix's gmtime function. I was interested in the bit that calculated the year number from days since epoch. Here are the guts of that bit: http://www.raspberryginger.com/jbailey/minix/html/gmtime_8c-source.html http://www.raspberryginger.com/jbailey/minix/html/loc__time_8h-source.html #define EPOCH_YR ...

XTS size limitation

Good morning, My question saga continues about R. I have been working on large datasets lately (more than 400 thousands lines). So far, I have been using XTS format, which worked fine for "small" datasets of a few tenth of thousands elements. Now that the project grows, R simply crashes when retrieving the data for the database and p...

Definitive function for get elapsed time in miliseconds

I have tried clock_gettime(CLOCK_REALTIME) and gettimeofday() without luck - And the most basic like clock(), what return 0 to me (?). But none of they count the time under sleep. I don't need a high resolution timer, but I need something for getting the elapsed time in ms. Thanks. EDIT: Final program: #include <iostream> #include <...

Timeserver update rate on Windows CE

I have a Windows CE box that doesn't seem to synchronise its settings with the time server. I have ensured it is on and set the refresh rate to be low (5minutes) yet it still doesn't update. Has anyone had any experience with this? If I refresh the service's settings using services refresh ntp0: it will instantly update the time setti...

Fastest timing resolution system

What is the fastest timing system a C/C++ programmer can use? For example: time() will give the seconds since Jan 01 1970 00:00. GetTickCount() on Windows will give the time, in milliseconds, since the system's start-up time, but is limited to 49.7 days (after that it simply wraps back to zero). I want to get the current time, or ticks...

Ok, so the situation is as follows. I have a server with services for a game, a particular command from the server sends a timestamp for when the next game round should commence. To get this perfectly synced on all connected clients I also have a webbservice that returns a timestamp of the servers current time. What I know: the time be...

Python checking daytime

Basically, I want my script to pause between 4 and 5 AM. The only way to do this I've come up with so far is this: seconds_into_day = time.time() % (60*60*24) if 60*60*4 < seconds_into_day < 60*60*5: sleep(time_left_till_5am) Any "proper" way to do this? Aka some built-in function/lib for calculating time; rather than just using s...

However, after some playing around I realized that it is not...

Embedded Python - Blocking operations in time module

Hi all, I'm developing my own Python code interpreter using the Python C API, as described in the Python documentation. I've taken a look on the Python source code and I tried to follow the same steps that are carried out in the standard interpreter when executing a py file. These steps (sequence of C API function calls) are basically: ...
