Comparing Time[0] to variable

[WalterSkinner]

if (DateTime.TryParse(trade21Datetime, out myDateTime21))
     Print("Parsed successfully:\t" + myDateTime21);
else
     Print("Unable to understand DateTime input.");


if(Time[0] == myDateTime21)
{
     Print("Current time equals myDateTime21");
}
Print("==========");
Print("myDateTime21: " + myDateTime21);
Print("Time[0]: " + Time[0]);

This is the output:

Parsed successfully: 1/20/2022 9:07:06 AM
==========
myDateTime21: 1/20/2022 9:07:06 AM
Time[0]: 1/20/2022 9:07:06 AM

Can someone please help me understand why "Current time equals myDateTime21" doesn't print? When I print out Time[0] and myDateTime21 they appear to match, but when I compare them in the if statement they don't seem to be equal.

Then they are not equal
Try to out them with milliseconds.

Thanks for your reply.

The variable comes from a spreadsheet and the granularity is seconds, are you aware of a way to chop off the milliseconds?

Or perhaps there's another way?

Here's a workaround that might suffice for now:

if (DateTime.TryParse(trade21Datetime, out myDateTime21))
     Print("Parsed successfully:\t" + myDateTime21);
else
     Print("Unable to understand DateTime input.");


if(Time[0] <= myDateTime21.AddSeconds(1) && Time[0] >= myDateTime21.AddSeconds(-1))
{
     Print("Current time equals myDateTime21");
}
Print("==========");
Print("myDateTime21: " + myDateTime21);
Print("Time[0]: " + Time[0]);

Output:

Parsed successfully: 1/20/2022 9:07:06 AM
Current time equals myDateTime21
==========
myDateTime21: 1/20/2022 9:07:06 AM
Time[0]: 1/20/2022 9:07:06 AM

Or like this:

DateTime time0 = Time[0].AddTicks(Time[0].Ticks % TimeSpan.TicksPerSecond);

if(time0 == myDateTime21)
{
Print("Current time equals myDateTime21");
}

Hello WalterSkinner,

You would need to create a new DateTime object if you wanted to chop the seconds off.

DateTime myDateTime = new DateTime(Time[0].Year, Time[0].Month, Time[0].Day, Time[0].Hour, Time[0].Minute)

Or you could subtract the seconds as you suggested.
