TimeSpan of days in configuration?
It appears that ConfigurationElement of TimeSpan cant handle values larger than 23:59:59. Are there any workarounds? Is subclassing TimeSpan, and making a new TimeSpanValidatorAttrib even going to work? I need to handle timespans from a few minutes to a few days. I'm using the following configuration section [ConfigurationProperty...

Formatting a negative TimeSpan
I'm doing some math with the Timespans in .Net, and occasionally the sum results in a negative Timespan. When I display the result I am having trouble formatting it to include the negative indicator. Dim ts as New Timespan(-10,0,0) ts.ToString() This will display "-10:00:00", which is good but I don't want to show the seconds so tri...

What exists in terms of a Java 'timeline' library?
I am interested in any library which can do the following: I have a time range: let's say 1995 to 2010 which I can classify in some way, let's say as "The Internet Era". I then want to be able to break that up further, say 2001-2010 as "The Google Era". Ideally, I'd like the time line to exist as some sort of list of timespans object...
TimeSpan and double rounding errors
Hello, I'm dealing with physical entities, such as time, speed and distance, and performing simple math, such as distance = time * speed, etc. Speed and Distance are double values rounded to 8th digit, and for Time values a .NET TimeSpan is used. Since TimeSpan rounds to a closest millisecond, I'm getting rounding errors, so I need to w...
Why has this particular TimeSpan format string stopped working in .NET 4?
Consider this code (prestuffed with an example): DateTime dt1 = DateTime.Parse("7/30/2010 9:33:29.1234567 AM"); DateTime dt2 = DateTime.Parse("6/30/2010 9:33:00.7654321 AM"); TimeSpan ts = dt1 - dt2; Console.WriteLine(string.Format( "{0:d.hh:mm:ss.ff}", ts )); This is representative of a piece of code that I've had working since .NE...
is there a smarter way to generate "time since" with a DateTime objects
i have this code to take a time in the past and generate a readable string to represent how long ago it was. I would have thought Timespan.Hours would give you hours even if its multiple daye in the past but it looks like it breaks it down into its seperate components (days, months, etc). How would i get total hours ago (even if its mo...
Calculating timespans for outages when I have only the results of failed calls
I'm writing a report that shows total downtime for our website. When a user visits our site and something's not working (ie the load balancer thinks our site isn't responsive), it sends visitors to a "Maintenance" page. The maintenance page logs to the database that it's been viewed and displays a friendly message to the visitor. That m...
Different behaviour between formatting strings for TimeSpan and DateTime
Hi all! While coding today, I noticed something odd with timespans and formatting strings. I was trying to print a timespan, for instance 01:03:37 as 1:03:37 (without the leading 0 for hours). So I used the format string h:mm:ss. This, however, gave me a leading 0. If I converted the TimeSpan to a DateTime and did the same thing again, ...
What is the proper way to format a TimeSpan as a countdown timer?
I have a timer that runs on the website. It will retrieve a timespan of how long a user has until their order expires. For the most part this works fine, the server will return the initial time remaining and the javascript will do the countdown. So it displays 2:30 2:29 2:28 Then for some reason, on some of the page loads (seems to hap...
How can a Timespan-Day last only for 8 Hours?

Arithmetic with PowerShell Timespans
PowerShell Timespans are great for quickly displaying durations, as in: $starttime = $(get-date) { do some processing here } write-host "Duration: $((new-timespan $starttime $(get-date)).tostring())" But if I did $loopcount iterations of processing during that timeframe, how do I divide the duration by $loopcount to get the average du...
