| | | * Provides a parser and evaluator for unix-like cron expressions. Cron |
| | | * expressions provide the ability to specify complex time combinations such as |
| | | * "At 8:00am every Monday through Friday" or "At 1:30am every |
| | | * last Friday of the month". |
| | | * "At 8:00am every Monday through Friday" or "At 1:30am every |
| | | * last Friday of the month". |
| | | * <P> |
| | | * Cron expressions are comprised of 6 required fields and one optional field |
| | | * separated by white space. The fields respectively are described as follows: |
| | | * |
| | | * |
| | | * <table cellspacing="8"> |
| | | * <tr> |
| | | * <th align="left">Field Name</th> |
| | |
| | | * </tr> |
| | | * </table> |
| | | * <P> |
| | | * The '*' character is used to specify all values. For example, "*" |
| | | * The '*' character is used to specify all values. For example, "*" |
| | | * in the minute field means "every minute". |
| | | * <P> |
| | | * The '?' character is allowed for the day-of-month and day-of-week fields. It |
| | |
| | | * Wednesday, and Friday". |
| | | * <P> |
| | | * The '/' character is used to specify increments. For example "0/15" |
| | | * in the seconds field means "the seconds 0, 15, 30, and 45". And |
| | | * in the seconds field means "the seconds 0, 15, 30, and 45". And |
| | | * "5/15" in the seconds field means "the seconds 5, 20, 35, and |
| | | * 50". Specifying '*' before the '/' is equivalent to specifying 0 is |
| | | * the value to start with. Essentially, for each field in the expression, there |
| | | * is a set of numbers that can be turned on or off. For seconds and minutes, |
| | | * is a set of numbers that can be turned on or off. For seconds and minutes, |
| | | * the numbers range from 0 to 59. For hours 0 to 23, for days of the month 0 to |
| | | * 31, and for months 0 to 11 (JAN to DEC). The "/" character simply helps you turn |
| | | * on every "nth" value in the given set. Thus "7/6" in the |
| | | * month field only turns on month "7", it does NOT mean every 6th |
| | | * month, please note that subtlety. |
| | | * month field only turns on month "7", it does NOT mean every 6th |
| | | * month, please note that subtlety. |
| | | * <P> |
| | | * The 'L' character is allowed for the day-of-month and day-of-week fields. |
| | | * This character is short-hand for "last", but it has different |
| | | * meaning in each of the two fields. For example, the value "L" in |
| | | * the day-of-month field means "the last day of the month" - day 31 |
| | | * for January, day 28 for February on non-leap years. If used in the |
| | | * day-of-week field by itself, it simply means "7" or |

| | | * for January, day 28 for February on non-leap years. If used in the |
| | | * day-of-week field by itself, it simply means "7" or |
| | | * "SAT". But if used in the day-of-week field after another value, it |
| | | * means "the last xxx day of the month" - for example "6L" |
| | | * means "the last friday of the month". You can also specify an offset |
| | | * from the last day of the month, such as "L-3" which would mean the third-to-last |
| | | * day of the calendar month. <i>When using the 'L' option, it is important not to |

| | | * from the last day of the month, such as "L-3" which would mean the third-to-last |
| | | * day of the calendar month. <i>When using the 'L' option, it is important not to |
| | | * specify lists, or ranges of values, as you'll get confusing/unexpected results.</i> |
| | | * <P> |
| | | * The 'W' character is allowed for the day-of-month field. This character |
| | | * is used to specify the weekday (Monday-Friday) nearest the given day. As an |
| | | * example, if you were to specify "15W" as the value for the |
| | | * The 'W' character is allowed for the day-of-month field. This character |
| | | * is used to specify the weekday (Monday-Friday) nearest the given day. As an |
| | | * example, if you were to specify "15W" as the value for the |
| | | * day-of-month field, the meaning is: "the nearest weekday to the 15th of |
| | | * the month". So if the 15th is a Saturday, the trigger will fire on |
| | | * the month". So if the 15th is a Saturday, the trigger will fire on |
| | | * Friday the 14th. If the 15th is a Sunday, the trigger will fire on Monday the |
| | | * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. |
| | | * 16th. If the 15th is a Tuesday, then it will fire on Tuesday the 15th. |
| | | * However if you specify "1W" as the value for day-of-month, and the |

| | | * 'jump' over the boundary of a month's days. The 'W' character can only be |

| | | * specified when the day-of-month is a single day, not a range or list of days. |

| | | * <P> |
| | | * The '#' character is allowed for the day-of-week field. This character is |
| | | * used to specify "the nth" XXX day of the month. For example, the |
| | | * value of "6#3" in the day-of-week field means the third Friday of |
| | | * the month (day 6 = Friday and "#3" = the 3rd one in the month). |
| | | * Other examples: "2#1" = the first Monday of the month and |
| | | * used to specify "the nth" XXX day of the month. For example, the |
| | | * value of "6#3" in the day-of-week field means the third Friday of |
| | | * the month (day 6 = Friday and "#3" = the 3rd one in the month). |
| | | * Other examples: "2#1" = the first Monday of the month and |
| | | * "4#5" = the fifth Wednesday of the month. Note that if you specify |
| | | * "#5" and there is not 5 of the given day-of-week in the month, then |
| | | * no firing will occur that month. If the '#' character is used, there can |
| | | * only be one expression in the day-of-week field ("3#1,6#3" is |
| | | * only be one expression in the day-of-week field ("3#1,6#3" is |
| | | * not valid, since there are two expressions). |

| | | * <!--The 'C' character is allowed for the day-of-month and day-of-week fields. |
| | |
| | | * <P> |
| | | * The legal characters and the names of months and days of the week are not |
