# Time
# Goal and use
The Time component allows you to schedule start times for flows.
# Credentials and connection data
This component does not require credentials.
# Triggers
Triggers are the starting points of a flow. The Time component offers the following triggers:
| Name | Event |
|---|---|
| Scheduled trigger | Started via cron expression. |
Use:
Define when to start the flow via a cron expression. ELO Flows uses the Spring cron format with a seconds field. This expression has six fields.
# Structure
| Second | Minute | Hour | Day of month | Month | Day of week | |
|---|---|---|---|---|---|---|
| Mandatory | YES | YES | YES | YES | YES | YES |
| Permissible values | 0-59 | 0-59 | 0-23 | 1-31 | 1-12 or JAN-DEC | 1-7 or MON-SUN |
| Permissible characters | , - * / | , - * / | , - * / | , - * ? / L | , - * / | , - * / L |
Please note
Fields cannot be allocated twice. Double allocation such as 0 * * * * * does not work here.
You can increase the complexity of the cron expression with the following characters:
| Character | Meaning | Example |
|---|---|---|
* | All values | * in the minutes field = Every minute |
? | No specific value | 0 0 * ? * * = Every hour, no matter the day |
- | Range between two values | 0 0 10-12 ? * * = Every hour between 10:00 and 12:59 |
, | Additional values | 0 10,44 14 ? * * = At 14:10 and 14:44 |
/ | Incremental values | 0 0/5 * * * ? = Every 5 minutes |
L | Last value | * * * L * ? = Every second on the last day of the month |
