index.xts incompatible with PerformanceAnalytics charts.PerformanceSummary

[jswift24]

Following up on this issue...
#2

Here's an example to reproduce the problem:

library(PerformanceAnalytics)
example(charts.PerformanceSummary)

works

setInternet2(TRUE)
con = gzcon(url('https://github.com/systematicinvestor/SIT/raw/master/sit.gz', 'rb'))
source(con)
close(con)

example(charts.PerformanceSummary)

generates an error: Error in xts(rep(NA, length(time(x))), order.by = time(x)) :

order.by requires an appropriate time-based object

rm(index.xts)

example(charts.PerformanceSummary)

works again.

The code crash is inside the function
chart.BarVaR, at line 47.
chart.BarVaR is called by charts.PerformanceSummary.
The 'x' parameter in the function is the data 'edhec',
so I can substitute it.

At approx line 34 of chart.BarVaR, is this conversion:
time(x) = as.Date(time(x))
Compare results:
without SystematicInvestor,

class(time(edhec))
[1] "Date"

and

xts(rep(NA,length(time(edhec))), order.by = time(edhec))
works okay.

But with SystematicInvestor, as.Date() has a different
class:

class(time(edhec))
[1] "POSIXct"

xts(rep(NA,length(time(edhec))), order.by = time(edhec))
Error in xts(rep(NA, length(time(x))), order.by = time(x)) :
order.by requires an appropriate time-based object
