Easy Chart. Export to excel

I have a problem with exporting data from chart to excel.
It is Ignition 7.7.5 on Linux OS.
In exported excel file “t_stamp” column contains dates with zero time (“02-01-2017 00:00:00”). Dates are right but time in each row is 00:00:00.
Could someone help to solve it?

What is the tag history resolution and resolution mode set to on the easy chart? This will effectively determine the time between the records that are returned from its historical query.

If you find that the xls is returning this way regardless of this setting, then a better option will be to make a new button with a script that performs its own tag history query and saves an Excel file, using the system.tag.queryTagHistory() and system.dataset.exportExcel() functions.
