I need to convert double with number of seconds since the epoch to ptime. I'm prety sure there must be an easy way to do this, but I couldn't find anything. Thanks.
Edit: The original timestamp is floating point. I can't change it and i don't want to lose the sub-second precision.
after some fiddling around i came up with this:
ptime(date(1970, 1, 1), time_duration(0, 0, 0, time_duration::ticks_per_second() * 1234567890.0987654321))
I'm not sure this is the best solution, but it seems to do what i need.
