Dear all,

With the following `psbasemap` call:

```
psbasemap -JX10/5 -R2022-11-15T/2023-01-15T/2000/7000 -Bpxa7Rf1d -Bsxa10 -Byf500a1000 -BWenS > ps

```

the output PS file seems to be erroneously big (50 MB), what am I missing here? In `gmtdefaults` I have:

```
FORMAT_TIME_PRIMARY_MAP = Character
FORMAT_TIME_SECONDARY_MAP = full
FORMAT_TIME_STAMP = %Y %b %d %H:%M:%S
TIME_EPOCH = 1980-01-01
TIME_IS_INTERVAL = off
TIME_INTERVAL_FRACTION = 0.5
TIME_LEAP_SECONDS = false
TIME_REPORT = none
TIME_UNIT = s
TIME_WEEK_START = Monday
TIME_Y2K_OFFSET_YEAR = 1950

```

Thanks for any pointers.

GMT 6.4.0 in WSL2.
