Incorrect time coordinate when running at a single grid cell

[SeanBryan51]

In the following code, it looks like the if condition will incorrectly assign a local time coordinate (for site configurations) if we run at a single grid cell with a spatial configuration other than cable_user%MetType = 'gswp'.

CABLE/src/offline/cable_input.F90

Lines 832 to 836 in f603fc5

	IF(mland_fromfile==1.AND.(TRIM(cable_user%MetType) .NE. 'gswp')) THEN ! If single site, this is local time
	time_coord = 'LOC' ! 12am is 12am local time, at site/gridcell
	ELSE ! If multiple/global/regional, use GMT
	time_coord = 'GMT' ! 12am is GMT time, local time set by longitude
	END IF
