Is there a better way to trim a DateTime to a specific precision?
.net, c#, datetime
Solution
static class Program
{
//using extension method:
static DateTime Trim(this DateTime date, long roundTicks)
{
return new DateTime(date.Ticks - date.Ticks % roundTicks, date.Kind);
}
//sample usage:
static void Main(string[] args)
{
Console.WriteLine(DateTime.Now);
Console.WriteLine(DateTime.Now.Trim(TimeSpan.TicksPerDay));
Console.WriteLine(DateTime.Now.Trim(TimeSpan.TicksPerHour));
Console.WriteLine(DateTime.Now.Trim(TimeSpan.TicksPerMillisecond));
Console.WriteLine(DateTime.Now.Trim(TimeSpan.TicksPerMinute));
Console.WriteLine(DateTime.Now.Trim(TimeSpan.TicksPerSecond));
Console.ReadLine();
}
}
Problem
What's the best way to trim a DateTime object to a specific precision? For instance, if I have a DateTime with a value of '2008-09-29 09:41:43', but I only want it's precision to be to the minute, is there any better way to do it than this? ``` private static DateTime TrimDateToMinute(DateTime date) { return new DateTime( date.Year, date.Month, date.Day, date.Hour, date.Minute, 0); } ``` What I would really want is to make it variable so that I could set its precision to the second, minute, hour, or day.
