Doesn’t look like there is anything built-in (you can use zz
, but that leaves out the minutes).
You can roll your own by instantiating a DateTimeFormatInfo
, setting TimeSeparator
to string.Empty
and using that as the IFormatProvider
when calling DateTime.ToString
(and make the call explicit, if it is not already).
But frankly, using Replace
to remove the unwanted :
from the default return value is so much easier.
