    <p>Are you just setting up this service? If so, <strong><em>run your web servers and database servers on Universal Time Coordinated</em></strong> (UTC or Zulu) time, not a local time zone. Everything is far easier to manage if you do that. I learned this the hard way. </p> <p>UTC used to be called Greenwich Mean Time; it is timezone +00:00. It doesn't change for daylight savings time like US and European local time does.</p> <p>This time zone thing is a pain, and worth getting right. Some countries have half-hour time zones.</p> <p>At any rate, once you know each user's preferred time zone, and the time she wants her notification, you can then convert the time from local to UTC and store it.</p> <p>Try something like this to get the user's hour and minute into UTC. (Time zone conversions need a date, because they depend on daylight savings time rules. There's one more complication. On the day when a time zone switches from daylight to standard, or vice versa, the UTC time for a notification will change. Most people handle this by recomputing the UTC date and time of the next notification (tomorrow's notification) as they send each notification. Consider this code.</p> <pre><code>TimeZoneInfo userLocal = ;//user's time zone int hour = ;//whatever the user wants int minute = ;//whatever the user wants DateTime tomorrow = DateTime.Now.AddDays(1); int year = tomorrow.Year; int month = tomorrow.Month; int day = tomorrow.Day; DateTime notificationTime = new DateTime(year,month,day, hour,minute,0, DateTimeKind.Unspecified); DateTime tomorrowNotificationTime = TimeZoneInfo.ConvertTimeToUtc( notificationTime,userLocal); </code></pre> <p>This should get you the UTC time you need to deliver this user's notification tomorrow, in the correct time zone for tomorrow's date.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
