Dear MIDAS experts, 

I confirm that when writing out history files corresponding to the slow control event data, 
MIDAS history system timestamps the data not with the event time coming from the event data, 
but with the current time determined by the program - 

https://bitbucket.org/tmidas/midas/src/293d27fad0c87c80c4ed7b94b5c40ba1e150bea4/progs/mlogger.cxx#lines-5321

where 'now' is defined as  

time_t now = time(NULL);

I'm looking for a way to timestamp the history data with the event time - that is important 
for HEP applications outside the DAQ domain. Yes, MIDAS infrastructure is very well suited for that, 
there could have a number of such applications, and experiments could significantly benefit from that.

So I'm wondering whether the implementation is a design choice made or it could be changed. 

The change itself and especially its validation may require a non-negligible amount of work - I'd be happy to contribute.

Any insight much appreciated.
