Answer 1

Assuming this is C# (looks like it is) and it is running on the server (not actually in the browser): You should check to see what the value of System.Globalization.CultureInfo.CurrentCulture is. See if it is different for a request coming from IE vs one of your other browsers. DateTime.TryParse(string, out DateTime) uses this value to help parse the string.

For instance, the date you provided: "28/04/2015 07:59:00" will cause TryParse to return false if the current culture is en-US , but if the current culture is es-MX , then it will return true .

I'm not sure why it would be different between browsers off the top of my head, but it's at least a place to start looking.

I came across a similar issue and the issue was the javaScript method toLocaleDateString() in IE11 return string with some RTL characters! which results in invalid data and these characters aren't visible.

A simple fix using regex

toLocaleDateString().replace(/[^A-Za-z 0-9 \\.,\\?""!@#\\$%\\^&\\*\\(\\)-_=\\+;:<>\\/\\\\\\|\\}\\{\\[\\]`~]*/g, '')

I tried the same regex at the back C# but it didn't work, however, I didn't want to spend more time on this so I just applied the front end solution.
