Cron Expressions
TeamCity allows you to flexibly schedule regular operations using the cron format. Currently, cron-like expressions are supported for schedule triggers and server clean-up.
TeamCity uses Quartz for working with cron expressions. See the examples below or consider using the CronMaker utility to generate expressions based on the Quartz cron format.
