sub_hour

Subtracts an hour from a date. The value must be of the form {{Y,M,D},{H,I,S}}.

For example:

{{ value|sub_hour }}

When the value is {{2008,12,10},{15,30,0}} then the output is {{2008,12,10},{14,30,0}}.

The filter has an optional argument which defines the number of hours to subtract:

For example:

{{ value|sub_hour:3 }}

When the value is {{2008,12,10},{15,30,0}} then the output is {{2008,12,10},{12,30,0}}.
