The invention discloses an alarm method and device, a storage medium and a
computer program product, and is applied to the field of
data processing, and the method comprises the steps: determining whether to adjust the original planned alarm time or not based on the planned time of a to-be-alarmed instance and the position relation between the original planned alarm time and a command
time switching interval; if it is determined that the original planned alarm time is adjusted, taking the adjusted original planned alarm time as the actual planned alarm time; if it is determined that the original planned alarm time is not adjusted, taking the original planned alarm time as actual planned alarm time; based on the
time difference between the business
system and the destination and the
daylight saving time starting and ending time of the destination, converting the
current time of the business
system into the actual local time of the current command of the destination; and judging whether the actual planned alarm time is greater than the actual local time or not, if not, giving an alarm to the alarm instance, and if yes, not giving an alarm to the alarm instance.
