This is my preference:
if (t > 255)
t = (((t - 1) / 60) + 1) * 60;
Which basically is a round-up to minutes
t = 256 -> gives 300
t = 299 -> gives 300
t = 300 -> gives 300
t = 301 -> gives 360
t = 15299 -> gives 15300
t = 15300 -> gives 15300
t = 15301 -> gives 15360
So I am also for going late.
Kind regards,
Wim.
