The ParseTime() function looks strange, since it converts relative duration to absolute time since Unix Epoch.
In most scenarios such a conversion is used by mistake.
It is better to do not expose such a function for public use and hide it inside the package where it is needed,
e.g. inside app/vmalert-tool/unittest.
