I have a process that sends files to a separate system in bulk and I want to spread the file sending out over time so as not to overload the receiving system (# of connections). I am using a timer when the user finishes their process to schedule the sending at a later time. I'm upgrading the logic to move the time from midnight (the day after the user finishes their work, based on business needs) to between 4-5:30am on that same day.
=rule!ART_GetDateTimeMidnightOfGivenDateAndNumDays(ri!dateTime,2) + 0.1667 + (0.06*rand())

Question: Is there a simple way to get a timer to run on increments less than 1 minute? Right now with 100 or so transactions occurring over the 90 minute window there is a chance the rand() function will allow a few to occur the same minute. I'd like the timer to work at say 4:35:23 and 4:35:47, so that they are less likely to step on each other.

Can the timer or clock in Appian work at the second level?...

I'll have to give the seconds part a shot again, since my test outputs didn't show seconds I assumed the timer was ignoring them. I am contemplating a rewrite to work on a queue system as you suggested. This would be a better long term way to go. Short term I was hoping to use the existing timer solution and throw in a quick rand() function to spread the attempts out over 1-2 hours since this is happening in the middle of the night and isn't time critical. I have the rand() working in test now and it was a quick fix.
