Remarks

Extended format syntax :

Minute - 0-59
Hour - 0-23
Day of month - 1-31
Month - 1-12
Day of week - 0-6 (Sunday is 0)
Wildcards - * means run every
Examples:
* * * * * - expires every minute
5 * * * * - expire 5th minute of every hour
* 21 * * * - expire every minute of the 21st hour of every day
31 15 * * * - expire 3:31 PM every day
7 4 * * 6 - expire Saturday 4:07 AM
15 21 4 7 * - expire 9:15 PM on 4 July
Therefore 6 6 6 6 1 means: • have we crossed/entered the 6th minute AND • have we crossed/entered the 6th hour AND • have we crossed/entered the 6th day AND • have we crossed/entered the 6th month AND • have we crossed/entered A MONDAY? Therefore these cases should exhibit these behaviors: getTime = DateTime.Parse( "02/20/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/07/2003 07:07:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 1", getTime, nowTime ); TRUE, ALL CROSSED/ENTERED getTime = DateTime.Parse( "02/20/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/07/2003 07:07:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 5", getTime, nowTime ); TRUE getTime = DateTime.Parse( "02/20/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2003 06:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 *", getTime, nowTime ); TRUE getTime = DateTime.Parse( "06/05/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2003 06:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 5", getTime, nowTime ); TRUE getTime = DateTime.Parse( "06/05/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2005 05:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 1", getTime, nowTime ); TRUE getTime = DateTime.Parse( "06/05/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2003 05:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 1", getTime, nowTime ); FALSE: we did not cross 6th hour, nor did we cross Monday getTime = DateTime.Parse( "06/05/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2003 06:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 5", getTime, nowTime ); TRUE, we cross/enter Friday getTime = DateTime.Parse( "06/05/2003 04:06:55 AM" ); nowTime = DateTime.Parse( "06/06/2003 06:06:00 AM" ); isExpired = ExtendedFormatHelper.IsExtendedExpired( "6 6 6 6 1", getTime, nowTime ); FALSE: we don’t cross Monday but all other conditions satisfied
