[systemd-devel] systemd unit timer

[Vini Harimoorthy]

In that case, it will run only in Oct,Nov, & Dec. But, I want to run the
timer unit weekly after a specific calendar date & time.
How to specify if I want to run some task on every 12 hours after Jan'2021
(start from future date & time)

Are the below requirements possible with a systemd timer ?

Let say, Current  date & time is :   2020-08-09 12:00:00
1) Run the task  every 1 hr starting from tomorrow
2) Run the task every 1 hr after  2020-08-09 15:00:00
3) Run the task on 2nd & 3rd day of the month after 2020-10-01

Basically, I want to specify the future time as start time of the timer
unit and the other specifications mentioned in onCalender has to be
executed after the start time


Thanks,
Vinitha
