Question

To populate my database I have been using the builtin SQLite command for datetime:

INSERT INTO samples (timestamp, sample_value) Values(datetime('now','localtime'), ...)

When I look at this on my Mac using a SQLite Reader called Base I see the following timestring:

2011-06-20 13:18:14

When I debug my vb.net program this line:

ts2 = CStr(r("timestamp"))

gives me

6/20/2011 1:18:14 PM

To parse this I have been using:

 ts = DateTime.ParseExact(ts2, "M/d/yyyy H:mm:ss tt", _
                                     System.Globalization.CultureInfo.CurrentUICulture)

This works for readings at 12:00:00 PM, but once I get to 1 PM I get a System.FormatException: String was not recognized as a valid DateTime.

Is this a UI formatting difference between PC and Mac? What might be going on?

Answer 1

I think you want h opposed to H in your format string. Try "M/d/yyyy h:mm:ss tt"

h is is 12 hour format while H is used in 24 hour format and your string 6/20/2011 1:18:14 PM requires h.
