<Chrono>.End	Stops a stopwatch and returns the time elapsed (in milliseconds) since the start of timing (call to <Chrono>.Start).
<Chrono>.Pause	Pauses a stopwatch in order to measure the time spent on a process.
<Chrono>.Reset	Stops and resets a running stopwatch.
<Chrono>.Resume	Resumes a stopwatch previously stopped by <Chrono>.Fin or <Chrono>.Pause.
<Chrono>.Start	Starts a stopwatch to measure the duration of a process (in milliseconds) and resets a running stopwatch.
<Date type>.ToDay	Returns the day that corresponds to a given date.
<Date type>.ToDayInAlpha	Returns the name of the day that corresponds to a specified date.
<Date type>.ToInteger	Converts a date to an integer.
<Date type>.ToMonthInAlpha	Returns the name of the month that corresponds to a specified date.
<Date type>.ToString	Converts: a date to a string in the specified format. a date time to a string in the specified format.
<Date type>.ToWeekNumber	Returns the week number within the year that corresponds to the specified date.
<DateTime type>.ToEpoch	Converts a local datetime to Epoch format (number of time units since 01/01/1970 at 00h00 UTC).
<DateTime type>.ToReal	Converts a date and time to an 8-byte real.
<DateTime type>.ToString	Converts a DateTime to string in the specified format.
<Duration type>.ToString	Converts a duration to a character string in the specified format.

Training (WINDEV): WD Evaluation period

[ + ] This example explains how to limit the use of an application to a given period (evaluation period).
The following topics are presented in this example:
1/ the protection of an application for a given duration
2/ the management of the registry

Summary of the example supplied with WINDEV:
When this example is started for the first time, it is activated for an evaluation period set to 5 days.
The information regarding the date when it was first started is stored in the registry and a control key is used to check whether this date was not modified by the end user. At the end of the evaluation period, the application is locked, unless the end user provides the code for unlocking the application
