That would be surprising. See below:
Non-appropriate extent/resolution
$ gdal_translate test.tif N48E002.HGT -of srtmhgt -outsize 1201 1201 -a_srs
EPSG:4326 -a_ullr 2 49 3 48
Input file size is 20, 20
Warning 1: The corner coordinates of the source are not properly aligned on
plain latitude/longitude boundaries.
0...10...20...30...40...50...60...70...80...90...100 - done.
vs correct one:
$ gdal_translate test.tif N48E002.HGT -of srtmhgt -outsize 1201 1201 -a_srs
EPSG:4326 -a_ullr 1.9995833333333333 49.0004166666666666667
3.0004166666666666667 47.999583333333334
Input file size is 20, 20
0...10...20...30...40...50...60...70...80...90...100 - done.
