Do you mean time_t (I've never heard of t_time)? You'll need to call 
unixTimeToStdTime on a time_t if you want to pass it to SysTime's constructor. 
And if you need to be careful of time_t if you're on Windows, because 
Microsoft screwed it up (for some bizarre reason, they apply DST to time_t - 
DST in the _local_ time zone - making it so that the offset between the local 
time and time_t is always the same instead of making time_t UTC like it's 
supposed to be). std.datetime assumes that you're dealing with a true time_t 
which is in UTC if you give it a time_t. Also, if you haven't already, you 
should read this article on std.datetime:
