Convert seconds to a date string and vice versa

[Martha Amer]

Hello,

I have a device which stores time in its flash memory as the number of seconds since 01/01/1970. One of my roles is to get/set its time. I would like to know the most efficient code to convert the time collected from the device to a readable date, then convert the updated date back to number of seconds since 01-01-1970 before sending it to the device.

Thanks!

Mart

I don't know if it's the most efficient way, but something like this should work:

CultureInfo culture = CultureInfo.CreateSpecificCulture("en-US");
DateTime zeroPoint;
long seconds = numberOfSecondsReturnedFromTheDevice;
DateTime myDate;
try
{
   zeroPoint = DateTime.Parse("1/01/1970 00:00:00", culture);
   myDate = zeroPoint.Add(new System.TimeSpan(seconds*1000)); //timespan in miliseconds.
}
catch(Exception ex)
{
   MessageBox.Show("Parsing of date failure: " + ex.Message);
}

Thank you very much for your help!
