I was wrong - the resource starts in 15 minutes.
I found a matching entry in the log at the same time:
 grep '11:59.*900' /var/log/cluster/corosync.log
Jun 21 11:59:50 [23616] dev-cluster2-node4 crmd:     info: crm_timer_popped:       PEngine Recheck Timer (I_PE_CALC) just popped (900000ms)
Jun 21 11:59:54 [23616] dev-cluster2-node4 crmd:    debug: crm_timer_start:        Started PEngine Recheck Timer (I_PE_CALC:900000ms), src=220

But anyway, now I'm more interested in the question "why such behavior."
Please tell me which part of the documentation I have not read?
