Ganglia csv export gives timestamp as 1970-01-01 but not current time

Question

Ganglia csv export gives time stamp as 1970-01-01. But when I view ganglia webfrontend, it shows proper time. I check Ganglia-webfrontend code, it shows that it is getting this value from RRDtool. Any solution to this.

Ganglia Web Frontend version 3.6.1
Ganglia Web Backend (gmetad) version 3.6.0.
RRDtool version 1.5.4

Ganglia wiki gives latest timestamp but the one installed on my cluster gives 1970-01-01. So this means Ganglia has the feature to display latest timestamp but one install on my cluster doesn't support this feature. But this is the latest ganglia version I could get using apt-get. There is Ganglia-3.7.2 available but it is not install able using apt-get and facing some issue while installing using rpm. Any help

[Edit2]

When I check the Ganglia version on Ganglia-wiki, this is the version I found. Only difference is with the rrdtool version.
Ganglia Web Frontend version 3.6.1
Ganglia Web Backend (gmetad) version 3.6.0.
RRDtool version 1.4.7
