Mame time has all the power in the hands, so do not do it because you do not want.
Sliders do not allow you to change the frequency accurately ... because it changes only the first 2 digits ... and also does not allow saving configuration.
So that mame time added this option in sliders, if it is not possible to change the frequency accurately, nor is it possible to save the configuration made?
Since it has an option in sliders, why not improve it adding precision in the choice of frequency and allowing to save the configuration in archive .CFG?
It would appear the only way to change to exactly 60Hz it is to adjust the source file(s) to assign the Hz to exactly what you want, then.
MAME is only concerned about proper refresh rates reflected in the pcb's raw parameters including pixel clock speed, vblank/Interrupt timers and other settings to accurately reflect the emulated Hz. Sadly, you'll get no help with it from the official forums.. perhaps a derivative build may be interested in helping.
